    Help please c7 corvette lt1

    So i have a 2015 corvette z51 lt1 with long tube header, xpipe, aftermarket exhaust, kn air intake, bbk 95mm throttle body. I feel like the car is not reaching full potential. Could someone help me please and take a look at my tune. 2015 c7z51Jesus15c7MOTpopsandbangs.hpt

    Made a few edits for some better throttle response. Lowered your lo octane table so the knock sensors can do their thing. You were going about a burble tune in the wrong way which I learned too. The magic is in the long term spark tables not the hi lo tables. Also turned off COT assuming you dont have them with lt headers. Without a log I cant safely do much with your timing as far as power goes.2015 c7z51Jesus15c7MOTpopsandbangs rev1.hpt

    You're missing out on some low end torque and you shouldn't zero out the VPC timing if your cam is still programmed to move.

    This would be if you want pops and bangs all the time. 2015 c7z51Jesus15c7MOTpopsandbangs rev2.hpt The rev 1 file is only during let off of the accelerator
