2024 Duramax Tuning Guitar. I just purchased a new 2024 3500hd denali ultimate. Expect improved fuel economy, better towing performance with edge calibrations engineered and developed by diesel guys.
If you wanted to tune your truck right off the batt you would’ve needed to buy a 22 or older 21’ lm2 s&b intake, ppe hot/cold charge pipe,. For your 2024 duramax turbo, you want better performance without sacrificing the response and performance you often lose when upgrading to a larger turbo.
