Need Help with 408 Stroker LQ9 tuning
Can someone help us out, my friend got his 2007 Silverado SS 408 Stroker tuned by a local guy using HPTuners and he really messed up his truck. Hes on his 4th built transmission and we think hes tuning is partly to blame.
So I used my V2 to look at his tune and it shows a lot of out of range and I also noticed that his Cylinder Volume was still set at 746. I changed that to 836 and I multiplied the VE table by the difference in displacements, used a guide I found in the forum. That helped the truck run a lot smoother and powerful, but we still have a problem that when coming to a complete stop the engine will almost turn off. Im not too good at tuning gas vehicles, I bought my V2 to tune my Duramax, Can someone look at these tunes and see what we can fix to have a decent running vehicle. Any help will be greatly appreciated. thanks

Abi SS Fixed.tun what were currently running with the fixed Cylinder Volume and VE Table
