I've been having a blast tuning this ZR1 and beat a lot of people but when I run other Vettes I always get the launch but they still pull pretty close. Am I losing top end due to a bad trans? Or just shifting? I try to shift 500 RPM before Redline and I 2-3 Quickshift off the line. I trap 168-170 depending on shifts.
