    You should provide ALOT more info about this problem. Giving the bare minimum will only get very few answers.

    Like what you even drive and what's done to the motor etc etc etc etc etc etc etc etc.
    2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.

    If you don't post your tune and logs when you have questions you aren't helping yourself.

    its a 2012 gmc sierra crew cab 5.3 heads, cam, 3600 stall, 4.10 gears, precision turbo PT7475 12 psi. its a daily driver. While tuning the truck it started fine everytime i had to turn it off and even after the tune was done everything was normal. went out in the morning and the truck would crank rev to 3k and die and puff some smoke out
