Vette knocking
At low boost 7psi car does great. At 10 psi car knocks at full boost and pulls 4 deg timing. Air fuel is between 11.3 and 11.5 but when car knocks in 4th gear at 5ooo rpm air fuel jumps to 13.5. I really dont wont to run high octance gas all the time cause $$$, I think that would solve it, currently using 93 octane. Prob need to do a forged motor, but I'd like to see what the LS2 is capable of on stock bottom end. Guess I have met its limitations. Any advice???
