My 2000 Corvette is heavily autocross-ed (BS) and occasionally in 2nd gear, the car will not accelerate quickly when the tach is around 3500-4000 rpm. Since the season is over I was looking at several log runs. In checking the tune I noticed C3906 might be limiting my throttle from opening faster, I was wondering if I would be better off increasing the upper limits between 2800 rpm and 4800 rpm and having it go to 95 or 100% from 4800 and above?
