I love the owner brought it to get it tuned up ,😈😈😈🗿

[@goracebox]

Bro didn’t even drive it stock first, send straight to us 😭

[@dankolicious10]

Tune, or FBO Tune....Either way the S58 platform puts out impressive numbers.

[@goracebox]

We freakin love this platform!

[@octanetvchannel]

​@@goracebox Definitely would love to see some 60 to 130 and trap speed on this car! I love the content

[@goracebox]

It’ll run pretty similar times as our own M3 and M4 have done on the same stock turbo setup. The M4 did 9.9 sec 1/4 mile and 6.05 60-130 in 2000DA and summer heat, and our M3 we ran a 5.77 60-130 when it was cooler out and around 0 DA. All full weight cars and running 300tw street tires! You can see these runs in our previous videos. 🫡

This was a great video. Appreciate the time spent dynoing each step. Rarely see that.

[@goracebox]

Thank you! This took a few days to video but worth it! It’s helpful to see a baseline, so we have something to compare to instead of just showing the final tuned numbers.

[@luxr6107]

Another banger! Thanks for the great vid!

[@BulliKid]

good comparison!

[@ClintG-rh6kh]

Chris is a stud! Alabama Crimson Tide. Love seeing the stages guys! Good job with the video!

[@goracebox]

Thank you! Yea man Chris was actually one of our OG customers, one of the first Q’s Hussain tuned! Happy for the dude, he’ll for sure be enjoying this car.

Bro showing how sturdy his stuff is🙌🏿😎

[@goracebox]

Lmaooo I fully expected him to fall 😭

[@nnacpil]

I'm ordering a 2025 G80 6MT. I would like to come down from Fort Worth and have y'all do something similar. I haven't found a performance shop here in DFW with this kind of knowledge with the g8x.

[@goracebox]

That’s awesome, and thank you for the kind words! Please shoot us an email at [e-mail] or give us a call during business hours at 832-786-9038 so we can get you set up. We can answer any questions you may have about the tuning process and different aftermarket parts.

[@nnacpil]

@@goracebox It will be awhile before I will get it but I will definitely be contacting y’all in the future! In the mean time, I will be following your channel! Kudos!

90 WHP from a Stage 1 OTS map?!?! Jesus Christ

[@sosa3202]

When the facebook chat pops up in video 😂😂😂😂😂😂

[@goracebox]

Bruhhhh the gc needs to chill fr, always popping off at the worst time 😭

[@KingG82]

Great video! Same setup in the winter would it pick up some power if so around how much?

[@goracebox]

Yes it will make slightly more, the dyno corrections accounts a bit for the hot temps, but what it doesn’t account for is the IATs the car is seeing. So purely just from cooler ambient temps, we’ll see higher numbers in the cold. We will see once it cools down and we dyno more cars, but unfortunately here in Houston even the winter months are pretty warm lol. Either way, the dyno is just a tool for tuning, real performance is seen on the street or the track, track or Dragy slip is king. 🫡

S58’s are cheat codes

[@markmartinez8000]

Well done! What ethanol sensor did you use?

[@goracebox]

Tensility Motorsports flex fuel kit! Easy install and allows us to tune the car for flex fuel on MHD. 🫡

[@josephgarcia7296]

[@Bimmer_Bill]

@@goracebox gotta get mine done!

[@goracebox]

Hit us up, we can remote tune if ur not local, super easy to set up! 👉 email [e-mail] if u got questions.

[@Bimmer_Bill]

@@goracebox I’m in Orange County, CA. Gotta prepare for the 2 weeks downtime tho cuz of Femto. Got plenty of e85 and 100 octane gas in my area tho!

[@goracebox]

We can take care of the FEMTO process for u too. Once set up with us, we send DHL to pick up at ur place, and once done, it’s dropped off to u again. No need to send to us or a third party, the current wait time for the whole process is only 1 week (given that there’s no unexpected delays) from when DHL picks up, to drop off back to u. We just did one for a customer out of state and it came back same week! Email us!

[@youknowimwhite]

Wait, you can upglug a plug for rwd?

[@youknowimwhite]

Nevermind, realized it's rwd

[@goracebox]

On xDrive cars like this we unplug the transfer case to dyno the car on a 2WD dyno safely. Don’t do this for driving on the street lol, the car has a 2WD mode u can switch into for that.

[@vijaybowla5162]

So just unplugging the transfer case wire and dyno mode. That's it !!!

[@goracebox]

Yep, we do all the xDrive cars like this with no issues. 😎
