In this video, we review the upgrade "Stages" for cars that come with the B58 engine and expected power output.
"Stage 1" = Stock
"Stage 2" = Downpipe
"Stage 2+" or "Stage 2.5" = Downpipe + HPFP
"Stage 3" = Turbo Upgrade (Hyrbid or full turbo Kit)
In general, there's no need to upgrade your intake, charge pipe, or spark plugs.

This is pure gold Kevin! Thank you sir 🙏🏻
Keep it coming bud🚀
got my 2021 supra last year and im so glad u made your channel for the info
Fantastic info man
Thanks a lot for such informative video! Gonna boost my F32 to stage 2 soon!
Great video! Thank you for your contribution!
Solid info, thanks for making this
Loved this video. so much knowledge THANK YOU
Thanks for posting 👍
Amazing vid once again! 👍
Great video broski! 🤘😎
Bro, you give the best info, and to the point. I dig the channel. Keep it going. BTW what is your wheel set up?

Great Information brother, give thanks 🙏! I just bought a 2019 540i , thinking about stage one for starter
This guys a different breed, I watch these videos even tho I have a n54
Thanks so much for the support
Great video brotha
Great video! Going to go stage 1 on my m140i soon knowing that the engine is capable of much higher
Just did mine on Friday and damnnn that engine is sleeping in stock tune! Got my eyes on a sport cat and maybe a cat back.
Great video
Perfect video!!!
Do you have any experience with Hybrids ? I have a bmw G05 45e. Just got down pipes installed 300 cell, and looking at ECU tune and custom exhaust with GPF delete. Tuner states around 500-520hp for stage 1. Should be no issues with engine and transmission. Any comments here from your side ?
Right now I'm running a decend 440 hp stage 2 with about 635 NM of torque and it suits perfect for a M240i. Everything above is like just burning Tires for no reason unless you really wanna compete in Dragraces. Guys be safe out there and choose a good tire if you want to have performance for your HPs.
I am loving the b58 in my 440. Such a beautiful driving experience!
good for you, man! One day I'll join the club
@@jotabarberaIV Yes in due time you will! Prosperity!

Very clear and informative video, well done matey.
Been running just a remapped standard car for a year, 411bhp/576nm, and going for a 200c ell sports cat next month, hopefully 460-470bhp and 630nm.
I had a gain from 424 hp/590 Nm to 460hp/650Nm after stage 2 ( Wagner catted downpipe)
@@jarasw8226 Nice result Jaras, thanks for sharing.
My m240i made 421bhp and 471lb ft on MHD stage 2 with 100 cell cat, not sure 460-470 bhp is realistic unless you have 102 Ron/oct
@@b16dans I think 450+ is about right for a sports cat.
Mine was dyno'd on a very conservative dyno, and made 336bhp stock on 99ron V power. After a custom remap, it made 411bhp/576nm on the same day.
That was stock everything. The performance specialist I take my car to said 450 is a realistic number for a 200 cell sports cat and further remap, with 600 to 650 nm.
I have seen a few make 470-480 with a sports cat, but I think those figures are exaggerated by either roller riding, ambient temp lies in the calculations, etc.
420 REAL bhp is about the maximum for a stock car with a custom remap. So I think the map on yours is not very good mate to be honest, I'd get it to a trusted tuner for a custom map, several dyno runs with the map tweaked each time for maximum power staying within safe temp/timing/fuel limits.
@@DjNikGnashers I guess it also comes down to the dyno and the guy operating it but I was told by the tuner he has never seen 400whp from b58 stage 2 on his dyno. And my figures were slightly better than a bm3 stage 2 b58 he had in the day before
Keep up the work. Love your content coming from a 440i coupe owner

Excellent guide. No need for some knob driving around saying check out my MHD generic settings. 👍🏽
Thank you
The video is really useful. B58 stage 2+ also gives 450-480hp power. So how much power would the S58 give at different stages?
Dude where was this like 4 months ago?! good stuff man!
I have a BMW x4 M and I got a Downpipe and ecu tune and e25 and i got like 250 extra hp the mods are worth the cash
Best Video!
Personally I run Stage0+ (Soon Stage1) already got 300cell DP. I just can recommend the DP and xHP even for stock cars. It makes it much more responsive and shifting not only in Sport/Sport+ nicer but WAAAAY smoother in Comfort. Just get xHP.. Also reminder, you have to go ~60miles in comfort, no kickdown, no manual shifting, no sport mode after flashing xhp to let the transmission get new gear adoption values etc.
Can you explain stage0+. Is it like a custom map that is not as boosty as stage 1 maps?
@@baronmunchausen645 The engine comes from BMW in a lot of different models. In each model it has a different kind of power/software. Stage0+ is basically the highest setting that BMW provided for a model and you can use this values on your engine to.
It basically is stock, but not stock, if that makes sense
Yeah it's the MPPSK tune for F30.
You should do one on What are stock Drive train limits like axle ,and Diff, driveshaft etc
One question and a suggestion... can you run full E with a stage 2 LPFP upgrade (is that the only Upgrade needed)? the suggestion... would be awesome if at the end of the video when you flash up the tunes and the power output if you could add another column to provide approximate ET and mile per hour for each of the power levels. Some people chase Dyno numbers (which is silly as it's just a tuning tool and they vary) others chase performance numbers, so would be good to know for stage 1 OTS the typical car will run 12.2-12.5 @ 114-117 for example. appreciate your chanell!
New subb. I love the vid, thank you for all the info. Was considering changing out my charge pipe and down pipe on my 340 6speed before going stage 1. Was told the B58 charge pipes are stronger than previous gens so don’t really need to do it. Didn’t really plan on going past stage 1 but if i’m already swapping out down pipe and that’s the only mod necessary to go to stage 2 i mite as well. My question is, if i just swap my down pipe for a high flow catted one and go stage 2 i shouldn’t run into any problems rite? Also, what platform would you recommend? Been looking at MHD, and Bootmod3.
There's no need to replace the charge pipe. I have a video discussing that as well if you check my channel.
No issues with stage 2. Both Mhd and Bm3 are good Tuning software. Personally i like the interface of BM3 but you can download both apps to see which you prefer.
@@kern417 appreciate the prompt response. About to go check out the video now. Thank you.
I bought a used 540i with 60,000 miles and I’m contemplating just doing stage 1 . Ideally I’d like to drive this car a bit past 100k miles and I’m sure it can do it just fine.

Mr. Kern, Very informative video, I wanted to ask, at the end you posted some values, the gains in terms of HP depending on the stage, however, the cards for other videos linked are blocking the last two i think, anywhere else, i can go and see those?

I’m new to a boosted car and bmw. i just got a 2016 340i and I’ve been watching most of your videos. Is there a specific reason why we don’t need spark plugs? Your helping me learn so much about these cars btw 💪🏾!
I guess it just depends on mileage.
Hey man! Thanks for all the videos and forum discussions! Loving it. I have made my g30 b58 gen1 up until this point to stage2+, but now stuggling a bit with settings for MHD tune - particularly should I tick the box for TCU TQ limiter removal or not? In theory mhd says st2+ is up to 520hp and 720nm, so even in a worst case scenario i would imagine my engine will be exceeding 550nm limit of the torque (apparently stock is around 450nm so with st2+ should easily go beyond 550nm, shouldn’t it?). Thanks for help in advance and again, loving my car now and your videos helped a lot!
do you have xhp?
Just joined the b58 engine club(coming from an r35 GTR)...got a stage 2 tune with a catless downpipe in a x3 m40i..and boy, it gained 100 hp..doing about 3.7 sec to 60mph..loving it!! BTW, got the x3 m40i for the same reason I got the GTR, best value for your buck!
Got a 22 m40i and looking to go stage 2 in future. Is yours a 21? And what tune you go with?
@@SL0Z07 flash is MHD..the tune is custom by the tuner
@@SL0Z07 just went full e85 and added a high pressure fuel pump..doing 0-60 in 3.5 now

Hearing this stuff gets me excited 😁 I'm about to tune my X3 m40i as well. I can already tell the B58 in it is superior to the N55 in my M2!
Got my m240i with the b58 2 weeks ago with only 50k miles on it and just loaded it with stage 1 with intakes and DP along with xHP stage 1 and WOW, it literally feels like my chest is being pushed through the seat when you put your foot down at 40 mph
Would go stage 2 but wanna ease into the power haha, next month I'll load the stage 2 file with a exhaust system then once the performance is done because stage 2 will be more then enough for me, I'll do interior and exterior mods! :)
cool, enjoy it
Is the 550i clutch hold the torque from the stock turbo on stage 2+ and the GC+ on pump only ? Probably around 550whp or less
pops and bangs from the downpipe are great
On point with everything,very nice video,congrats. On an M340 with pure 800, downpipe, change pipe,hpfp, and a Trans tune , on 93, it is possible to run more than 600whp? And it’s a daily what should i upgrade more?
There are no hpfp upgrades for an M340. There is also no need for a charge pipe.
On 93 i wouldn't expect more than 550 but some people have pushed it further.
Will be buying my 4th BMW soon, God Willing. I have been Looking for something like this FOREVER !!!!!!!!!!! Your information flow matching the logical evolution of this engine is the absolute BEST
I have ever heard and believe me I have 2 Doctorates in You Tube. Thanks soo much for this !!!!
my m240i pushes a bit over 600hp on 98 with a Hybried Turbo a Dorch Stage 2 HPPF and a Catet Downpipe and im now going on E20-E30 and look what the Car is going to make
Hi! Can i put a better intake with the m performance kit? Does it work ? Or I have to change the exhaust system or downpipe? I Mean can i make stage 2 with the m performance exhaust?

I love you
Fck, these engines really sound like they're bulletproof for some minor mods. Never thought I'd see a turbo BMW be able to handle 500whp on stock internals. Crazy.
Hey man, wanted to start by saying fantastic video! Your B58 info is super streamlined and really easy to understand, especially for a beginner like myself. I wanted to ask your advice about my current setup, I currently have a 340iX 6MT with MPPSK (completely stock other than some head unit upgrades) and I am hoping to just go for 400WHP on 91 AKI. From my research the front transfer case and transmission can handle around 466 lb-ft so hopefully it wouldn't hurt the daily drivability and potentially increase highway fuel economy (if I am thinking about this right).
Would a stage 2 tune get me near that number assuming drivetrain loss. Also, total shot in the dark, do you know if there is a major difference between the AA and VRSF catted downpipes other than the price, I would assume they function similarly but I really don't know for sure.
It will get you close. AA is higher quality than VRSF but both get the job done.
Sorry for the dumb question, I’m not fully up to speed on tuning cars. What is an OTS tune? I’d like to get a stage 1 on my car and not sure how to go at it
OTS = off the shelf. It's basically a generic tune that's meant to work on most cars with similar modifications.
yaaa boiii!
I have a Vargas VTT GC on the way as well as a VRSF high flow catted DP. Would I be able to expect around 450 WHP from a OTS stage 2 93oct tune with this setup? I plan on getting a Dorch stage 1 and a custom tune eventually but just curious how these current mods will handle until then.
I believe they Dyno'd around that much
@@kern417 How much power can you reliably get from 93 oct with an upgraded turbo and hpfp?
Everything is in the end of the video
great break down. i know audi / vw stages like the back of my hand but now that i want to switch to the bimmer life this was invaluable for the b58
So the charge pipes are solid in the b58? i remember that being a big problem in the n55
Yes
@@kern417 do the charge pipes increase turbo sound and add any hp even 5? I know the intakes add about 3-5 and more sound depending on the brand.
In the video, when you're talking about up-grading internals and cracking intake manifolds are you referring to BHP or WHP??
Whp
@@kern417 Thanks
@kern417 Darnit! Just found out your in Cincy! I was there the other day getting a carbahn tune at jake Sweeney bmw… so far I have AWE exhaust with AA downpipe.
I got impatient and did the tune with 10 months of factory warranty left, but I also added the Carbahn matching warranty.
It’s not a huge bump, but enough to notice! In your opinion this should be a fairly safe and mild tune??
The plan is to switch to Ecutek or BM3 next year once warranty is done. Awesome content btw!
Yeah it's safe
I watched a video where a guy put n52 cams in his n55 because his car kept falling on its face close to redline and after he put those n52 cams in his car stayed up all the to red line
Do you have a preference between BM3 or MHD? I like the features each one has but I want to make the most reliable power I can using one of their OTS tunes, it does seem like bm3 isn’t as good with timing opposed to MHD. I can’t really find any solid Dyno comparisons between the two (stage 2 dyno numbers) but I plan on going Stage 2 for sure and possibly stage 2+ with HPFP to possibly run an e30 mix every so often.
They both produce similar numbers and both make safe ots maps
@@kern417 Do you have any thoughts if running a jb4 with catted downpipe and an upgraded hpfp? Is that possible or is a flash tune necessary to make that happen?
@@stevengooden7911 i believe they have backend flashes to take advantage of the TU pump but I would 100% recommend a flash tune instead. I don't see how it could work with an aftermarket HPFP since you need to change settings in the DME for them to work.
Do u think stock transmission and stock block engine can handle 730whp and 670wtq?
I have a carbon tune, vsrf catless dp, intake and dinan exhaust. Only able to run 91 octane. Would I get power gains just from installing a water injection kit? Is a water injection kit as good as doing the HPFP upgrade?
You can see gains from meth Injection but just injecting water will not provide significant gains
Currently running a custom stage 2 tune, 455 hp and 618 Nm on my M140 Xdrive. Recently had the TU pump fitted as precaution. Is it worth re-tuning to stage 2+? Will the power gains be noticable from stage 2 to 2+ ?
With the TU pump it wont be that much but it would still be an upgrade over stage 2
I’m assuming these stages are different than a JB4 stage tune. Is it worth upgrading to an MHD over a JB4 if you have a catless down pipe/intake/charge pipes?
hell yes bro mhd will do ur car wonders if you already have supporting mods
Did you have to use an E92 M3 clutch MC conversion with a CDV delete to make your DocRace kit work?
No
Great way to save the intake manifold is to get an oil breather cap. Massively reduces the pressure
that's not how that works.
@@kern417 Reduces crank pressure which reduces pressure across the entire engine
@@saucysimpson259 the intake manifold is not connected to the crankcase
@@kern417 I know it's not but it reduces the pressure across the entire engine
What about downpipe on bm3 stage 1? Worried about putting the stage 2 with manual clutch. .🤔🤔🤔 Keep going with this b58 videos.
The manual clutch will hold stage 2 pretty well. Going above stage 2 e30 is when it tends to slip
How much torque can the 335i clutch hold?
Question, I have a 2019 440i coupe with tu hpfp, downpipe, and mhd stage 2+ tune running 93 octane. For the last 3 months the car has been running fine, do you guys recommend i get a transmission tune now or before i get my flex fuel kit to transition to e85? Thanks!
absolutely
What's your best recommended setup for a reliable ACN 91 octane flash and power ...have really terrible petrol quality here and I am contemplating a MPPSK for the sound and extra performance OR a stage 1 ACN OTS map with a catted downpipe
It just depends on your power goals. Any setup can be tuned safely on 91. But you can always buy ethanol online to run an e30 mix.
Do you have any info on a mission performance tune for a m340i? I have access to a local shop for a custom tune as well. Curious your thoughts on either of these. Thanks.
Bm3/mhd/mg flasher will be easier to use than those options.

Bro i want to get 20 inch wheels for my 340i xdrive. But i know it wont perform that well (getting a pure800 soon) Does it make a big of a difference? what do you think what i should do?
The weight will make the car accelerate slower and thinner tires will ride rougher but plenty of people do it. If the look is worth it to you then do it.
@@kern417 thanks bro imma go whit the 20 inch japan racing wheels.
And Do you perhaps know how to change the Digital Dash to White on Daylight? I find the orange pretty anoying makes the car look very old.
@@ilaomem no I'm not sure. If you turn off your automatic headlights it should stay white until you turn them on
hi, great info thanks, i have m240i manual with mhd stage 1 tune and a de cat downpipe , dont like the smell now so want to put std downpipe back in, does that affect the tune as stage one is generally ok with stock everything ?
Should be fine
thinking about getting a 540i and then taking it to 550hp and 800 nm how much would i have to spend?
Those power figures you post at end is that for rwd or awd applications. Big difference. If a stage 1 rwd is 380-400whp the awd version is at least 20hp less
No it's not
Still loving the content on this channel and please keep it up! I just installed MHD today on my 18' 340i RWD. I fitted the FTP chargepipe and intake pipe with a drop in BMC filter, catless downpipe and the TU pump. I went with 91 Oct stage 2 and did a dyno run. The results were a bit underwhelming 269wkw (361whp) and 587nm of torque. Do you think this is normal and could be a stingy dyno? Also the tuner that helped install my hardware said he does not recommend even loaded the stage 2+ even though I have the pump because in South Africa our fuel quality is poor. Would love to hear any thoughts on this.
How do the logs look? On 91 octane that's not bad.
@@kern417 it looks fine according to the tuner. There are some timing corrections. Boost is at 1.28.
Yeah probably just limited by octane. Just enjoy it 👍🏾
So please correct me if I'm wrong but... Aren't the ECU's in B58's built after 06/2020 locked and a bench unlock for the Dme is not yet possible? This leaves some of us with either Jb4 or racechip as an option? Or do you know something I don't?
Yes or you can send your dme to Femto in Russia for them to unlock it.

Sick video. I highly recommend an LSD to actually put that power down. Currently a stage 2 b58 with LSD + Trans tune as my next upgrade, then saving up for HPFP/turbo. I heard upgrading the heat exchanger is necessary in hot countries. Any idea how complex/expensive it is to strengthen the transmission?
LSD isn't really helpful for straight line performance. It's mostly for handling and traction out of turns.
I have a full heat exchanger Review wirh data on my channel if you scroll down through my videos.
Transmission build is expensive, but some people have swapped to the HP70 transmission from a 335d as a cheaper upgrade.
@@kern417 Your knowledge on the B58 is impressive, made my comment before realising the variety of detailed videos you have uploaded. Nice work!
As far as i know, LSD helps with traction in a straight line as well, especially from 0. Maybe im wrong idk
@@WhisperTheBand the main benefit of an lsd is transferring power from left to right. So unless there's a significant differential in traction between your left and right wheels then there aren't significant gains to be had. Modern Traction control does a lot to help you keep moving forward

Just got my 340i m sport about a month ago, what tuning company do you recommend? I’ve heard of mhd and bm3 but can’t decide on the two.
They both work well. Download both apps and see which interface you prefer. Also, if you plan on getting a custom tune in the future, check out the options and see if they lean to one or the other.
Hey looking to get a TU PUMP and help with where you buy one online would appreciated
Fascinated by the new M240i. Admired BMWs from afar, but never brave enough to venture into actually considering purchasing til now. How robust is the awd systems in these? Id be up to doing stg 2+ but limited to 91 octane as it would be my all weather daily.
They're good
It’s the best you can get. I had an 435i M Sport XDrive now i got a 440i Rwd and that M Sport would jolt off and suck you into the seat with INSTANT takeoff & speed
I have an 2017 M240i xdrive, im stage 1 no upgrades yet, I have DP and chargepipe that i’m about to get installed aswell as a dinan intake. Will that set me up for stage 2 and still be just as reliable as it is now? or should I get an intercooler as well? my tuner says I should but I hear many different opinions
im 9 months late but honestly the intercooler on the b58 is extremely solid, also for reliability this engine platform is proven to be hands down amazing for reliability while adding modifications. with a stage 2 you will be fine as long as you take care of your vehicle as you should be anyway.
What stage 1 tune do you recommend
Would you recommend Stage 3 Custom Big Turbo Kit for time attack track use on BMW 840i RWD ? Or Stage 2+ should suffice in terms of power efficiency (no wheel spin) ? Please advice, good people 😸
From what I have experienced when you want them suitable for track better is less hp cuz of less wheelspin and easier control of the gaspedal. But if you build it custom with everything needed suspenion tires and other stuff then 600hp is also okay but you will have problems with traction that is why I would stay with a stage 2 or stag 2+.
Hi, would you still need Xhp with stage 2+ please?
does stage 2 93 OTS with a catted downpipe for daily require clutch upgrade?
It should be ok on stage 2 93
Yes bro great videos only found you today but have subscribed and will be watching more of you ...
Can I ask you I’m in the uk I’ve got a b58 in a m140i f20/f21 I’m looking on going from stage 1 to stage 2 what is a good quality hpfp to go for ??
You can run stage 2 with stock hpfp
Sorry mate meant stage 2+
Ah ok, the TU pump is the best value

@@MikeSmith-kv7qm used they are ~$600
With the exception of geography in the engine bay. I would like to assume that most of this stuff can be done to my g05 x5 40i. Is that a correct assumption?
I have driven a modified 40i of a visitor to Toronto that hung out with us for a week. I could really feel it just tooling around Bloor St. I dont know what the mods were except he had a box inline for one thing. Other than that, you couldnt see anything. I would really like to do something to give it some oooomph once that thing is all mine in October.
Depending on the year it will be more difficult to tune
I have downpipe, intake, and active Autowerke stage 2 91 octane tune. If I wanted to reach 500+ what would be the most efficient way to reach that? Xhp flash and different fuel/tune?
If you want 500+ on 91 then you'll need a bigger turbo and custom tune. If you have e85 available then an e30-e50 mix can get you 470-500 on stock turbo with an upgraded hpfp.
Thank you for the informative posts. When it comes to the Supra B58, at what point or which case one would need to upgrade their fuel pump?
They dont have hpfp upgrades available for the supra
Already have the better tu pump in supra no?
@@davegotyou4511 they don't have *aftermarket hpfp upgrades but they come with the TU pump. Eventually you will need to add auxiliary injection to keep adding power.

I had a quick question regarding my manual 2018 340i. I got stage 2 E30 from BM3 running right now. I had an issue where I would go WOT and around 4k rpm or so the car would make loud pops and cut back on power. It wasn’t consistent. Sometimes it would happen and sometimes it didn’t. The RPM it would happen at would vary at times too but usually around 4k. At first I thought it was my clutch was slipping. So I had it replaced because it needed to be replaced anyways but that didn’t solve the issue. You got an idea of what that may be? I’m hoping it’s just me not having a good e30 mixture.
most likely, but you need to run a log to confirm.

Hi new subscriber here. Just purchased a 2018 440i xdrive convertible and being the gearhead that I am was looking for some performance mods associated with it. I see you mentioned a downpipe, wouldnt deleting the catalytic converters cause it to fail emissions? We are required to pass emissions here in PA...
it can. a tune will disable the code but won't show ready. an o2 spacer can prevent the sensor from picking up the missing downpipe but make sure it's not too long or it can create another CEL. you can also get a high flow downpipe that doesn't completely delete the catalytic converter but still flows more than stock.
@@kern417 cool, thanks for sharing
Can I get those tune from a bootmod3?...and can I upgrade down pipe...fuel pump if mt car is 2022...and I don't wanna flash computer yet..."warranty"
I heard it’s recommended to run ngk 1 step cold plugs is that true?
So does the "tune" only effect the sport mode? IE after you tune your car will running in the eco mode be the same if you are not looking to push it?
It affects all modes but eco mode is still slower and more economical
I just took my x3 m40i to a hub dyno it was making 455 to the wheel consistently
what upgrades?

Hi Sir, Can you guide me how to replace the heat management module?
I took it to our local BMW dealer and they said that it's check engine light because of heat management module is bad
Hello! What about the Air Intake? You have yours replaced, as we can see.
Currently running MHD stage 2 93 with catless downpipe and xHP stage 3. If I move to MHD stage 2+ with b58tu hpfp but stay on 93 without ethanol would it be worth it? Will the stage 2+ map give me more hp without running ethanol?
The HPFP is a big difference in Tq !
