my 95gt had an intake leak at the MAF...since I fixed it, my boost went from 4-5psi to 9psi. The car was dyno tuned for the 4-5psi. Now I get just a hint of detonation when I jump on it (especially when I'm in the 3-4k rpm area but it goes away about as quick as it started. I have the timing set to 10* The vaccumm is at -7 at idle..is this normal? Should I retard the base timing back? If I set the boost retard to 1.5 it gets better.
I have a msd distributor, 6btm and coil. pro-m 75mm, fms 65mm tb, gt40 intake and alm heads, 30# injectors, fms e303 cam, 1.7 rollers.
Any help would get great.
TIA
