I currently drive a 2022 Silverado 3.0L LM2 Stock Engine with 11184 miles (18000kms) on it. The best highway fuel economy I have achieved is 34 mpg. (6.9L/100kms.) Cruise Control was set at 74.5 mph (120 km/h) for 226 miles (363 kms), with perfect driving conditions - no wind, 46.4F (8C). Geographically - Jasper AB (elevation 3465.83 feet to Edmonton AB (elevation 2198.16 feet). In my opinion, I'd say this is quite outstanding fuel economy for a stock full size truck. I have no doubt in my mind, that the LM2 is GM's best engine built in the last 10 years. I enjoyed your review, and hope you share more information/updates for the LM2!
This gives me hope for the future. Have been afraid to ditch my 2.8L because no one was able to tune the 3.0. Would love to see a 325hp/600tq out of this platform.
Interesting video on the baby Duramax. I own a '23 Silverado 1500 RST with the LZ0. Very nice powertrain. Very smooth and quiet for a diesel with lots of torque and more than adequate horsepower for my needs. I get 16 mpg towing a 3500 lb travel trailer from Cali to Arizona and back (twice as good as the Frontier 4.0l V6 got) and get 28-30 mpg at highway speed. This truck drags the trailer up long/steep mountain passes at 65 mph with cruise control on effortlessly. The new baby Duramax does suck up lots of DEF while towing though.
I have a LM2 Silverado. Best powertrain I've ever had... Love the thing. Hope you guys make a tune for these things. I know one is out already but its from companies I've never heard of.
We do have 3.0L tuning for the 2020-2021! duramaxtuner.com/diesel-tuning/2-tune-pack-incl-tcm-tuning-unlock-your-ecm-credits-for-lm2-3-0-duramax-2020-2021.html
Brand new owner of the LZ0, 260 miles, lol. Would definitely be interested in a tune. Would it be a plug in module or a ECM flash? I don’t want to lose my warranty. Subscribed.
How much does it cost to have a tune like this done ? I have a 2021 with a s&b cold air intake, 6 inch lift with 22x33x12.50’s. Would love to have a little more torque and power.
@@nahbro3240 im in alberta, tons of deleted trucks. its not a matter of being scared, if you live in a place where you need emissions test to register your truck then you have to have it intact to be able to drive
So we r talkin 285/290hp to the rear wheels & 560ft/lbs of torque w/ this middle of the road tune!? That is awesome! Forget the LZ0 until there is a def delete cause stock it eats thru def so w/ a tune you will burn thru that 5 gallons in a tank of fuel! W/ that said, have you driven w/o your foot in it to see what kind of mpg you can get? Best I have is 34.4mpg w/ stock tuning, 4x4 SLT & 2” lift w/ 295/55/r20 tires
And that's hand calculated? On board computers tend to be optimistic! I've always had to have the dealer correct that under warranty (VW, Ford, and MB, all gas)...and Nissan dealer told me that it's supposed to be wrong lol!
Well your wrong, it does not eat thru DEF. A tank will last between 4000-5000 miles with normal driving. Hardly eating thru. Let’s stick with the facts shall we?
@@hammer-r mine does not get anywhere close to that and I will qualify as a mature driver, easy on the throttle with mostly hiway miles. 2500 miles for 2.5 gallons is what I'm figuring. My sons best friend's '23 is worse than my '22. Not sure how he drives but his truck has almost triple my mileage so more data.
@@denniswilliams2098 not sure what to make of your comment cause your calculation is in line with what I stated. I’m a mature easy going driver and yup about 5000 miles for a tank of def. But when I trailer like I have been, then it eats it much faster. But when I’m driving on the highway at 60 I’m getting about 40 mpg. So I can’t complain. My best 50 mile loop was 44.9 mpg. Best truck I’ve ever owned. But with everything, time will tell. But so far I love it. It’s a torque monster as I pull my 8000 rv up steep dirt roads camping.
@duramaxtuner you went over everything except the exhaust/discharge size. OD IS 3.75 correct? Do you know if it has a lip for the gt flanges or flat? Post a picture if you can, thanks
I've always been a duramax guy and have owned a 05 LLY and a 2015 LML, Both were super reliable. I'd be curious to find out the reliability on these baby duramax's and see if they are as good as the HD trucks
Unfortunately I bought a 21 with 12 thousand km on it last year. Had nothing but problems gm warranty wasn't helping me tried multiple dealers they were trying to delay me until my bumper to bumper ran out. Got tired of driving dealer rentals. Traded it in for a 21 ford f250 when I realized nobody was going to help me haven't looked back.
23’ lzo diesel, I was surprised my oil at 400 miles was blacker than my 2002 duramax has ever been, all those extra gasses can’t be good for the engine.
@Jakes videos Just cause it's black doesn't mean it's bad. Only way to find that out is thru oil samples. 200k on my 6.7 Ford and it turns black as soon as u start it after oil change. It's done it since it was new. I go 8k on oil changes and sample every oil change. It gets analyzed at my Local CAT dealer since that have the Lab right there
Please stop with the stupid comments about emissions on these pages! U only make it harder on everyone the more STUPIT people like yourself bring this up on public pages for anyone to see
I have a difficult quetion for you: whats the point of tuning a diesel? It will never feel like a gas. I have a new ecodiesel and i love the driving dynamics of the stock engine. Enjoy rolling down the road. Diesels are for towing and driving relaxed, not for racing..
@@Duramaxtuner everything in physics is a tradeoff. It is impossible to believe that the engineers gave up on better fuel economy and more power if there is no cost to pay in terms of reliability. You are trading durability for performance, thats what you are doing, but that's not my point. My point is that if u increase the performance of the diesel so much that it feels like a gas motor on the road, they it wouldn't feel like a diesel and would lose all of the appeal of driving a diesel. When u get an electric car u have better performance, but u miss the sound and the behavior of the internal combustion engine, don't u? Its the same when trying to improve the performance of a stock diesel.. There is a charm in the way diesels run..
Thanks for the video and how the turbo works. I’m very new to diesel trucks and bought a 2022 3.0 elevation 11:49 Duramax. Every once in a while my truck has light white mist or smoke From exhaust for about a minute when driving off. Only done this a few times and dealer can not find anything wrong and unable to duplicate the smoke. Goes away for a month or so and then happens out of nowhere. Someone said maybe the turbo, oil, fuel or coolant? Dealer said all good but happened again today? Any thoughts. Thanks
@Duramaxtuner I understand completely the driver has everything to do with MPG thank you for information and update me on way to take next steps for Horse Power
@jean-dominiquelaflamme5185 It's still in development. We have had so much tuning and turbo development this year it has been hard to get both the tuning and turbo for the LM2/LZO through our process together how we like to.

The recommended oil is junk. We have a couple of them in our fleet for work trucks they burn 5 qt of oil at the recommended oil intervals. Put 15w40 delo 400 Magically the oil consumption disappears doesn't even burn one qt of oil by the recommended oil change intervals and better MPG.
Don't go saying that it's gonna ruin the engine and the bearing and bearing clearance. They've been running strong no problems. Where it snows still good oil weight Any diesel engines a good idea to let it sit there and warm up.
Thinking about moving mine to 5w30 delvac esp, I wanted to go 5w40 turbo diesel but i thought itd be too thick. On the mobil 1 site alot of the diesel oils have basically the same specifications. On the 0w20 esp it says GMLicensed but have all the same specs as their 0w30 0w40 and 5w30 esp. Their all mid SAPS low ash low sulfer.

@jko0526 It's primarily cooled using engine coolant however the oil supply most likely provides some cooling as well. The placement and connection for the oil and coolant passages are quite interesting.

Yup, following. As a Yukon LM2 owner (future) i need me this. Thumbs up and subscribed.
I love your reviews
PPE makes an awesome intercooler for these 3.0s
LM2 had LOW AND high pressure EGR. low being post DPF high being pre. high is used typically to warm it up and is used ALOT in cold climates (alaska)
Thanks for the heads up!
Another great video! And nice Meyer Motors plate! That dealership is about 15 min from my house! 😁
Awesome video!
Awesome man
per a powertrain engineer WATCH teh head bolts. it was a concern during development.
I’m in the market for a LZO ! June is the month I’m buying! Love what the 3.0 L has to offer . Looking for a max tow package . Can’t find any .
Will your tune be available for the refresh trucks with the LM2 also? I know some of their PIDs are different.
I'm hoping the 2024 SUVs get the LZ0. Then I'm hoping you guys will have SUV/LZ0 tunes. Here's to hoping all the pieces fall into place...
Hopefully down the line!
What does that mean for LZ0? Really interested in seeing what can be done on top of what the manufacturer has already achieved.
Hopefully soon enough we will have access to that engine computer!
When can we see the new LZO?
The turbo may look easy to get to, but getting the DOC off is a huge pain
True story. I may have overestimated the accessibility of the turbo. Ha
Great article, now fix the L5P and L5D
Brand new owner of the LZ0, 260 miles, lol. Would definitely be interested in a tune. Would it be a plug in module or a ECM flash? I don’t want to lose my warranty. Subscribed.
It would be an ECM swap until a tuner can unlock without an ECM. Hopefully we get an LZ0 of our own soon.
how hard is this to do if we can not make the trip to your shop

We use HP Tuners.
I’m seeing SHITLOADS of 3.0’s on the road now. Products for this motor can’t come soon enough
Be on the lookout👀
Were can i buy this tune for. My lm2 been waiting on banks but they taking forever
We have tuning for the 2020-2021 3.0L. It's on our website duramaxtuner.com
Why don't u have a BANKS gauge on it to monitor the regens? This way u can prove u aren't making it regen more then stock settings?
What is the difference between this turbo and the 23s Turbo?
How did the tune effect fuel mileage?
With fuel economy-minded driving habits, 1-2 MPG gain.
Can you explain why you subtract 15 psi off the monitor to get the max boost psi?
Atmospheric pressure is around 14.7psi……. So it’s easier to say subtract 15 then 14.7
any updates/eta on refresh 22's?
Nothing yet. Trying to get our hands on an LZ0
