Why not go a bit more boost, keep her at a true 11.2 or 11.3 ish AFR and less RPM ( max of 6500 rpms and see how that compares) If it keeps true Knock from coming on , then there is less issue trying to get rid of it once it starts and self perpetuates. I wonder how much gain is or is not greatly seen at the 7500 rpm range vs. just adding a bit more boost starting at where the car's peak torque range begins, or about? 4200 rpms and up?

with the street cams the power curve should not end up to peaky-high RPM. So I shouldn't have to rev too high.
She is "quiet" up to 7K. It's after that it gets crazy. Those runs were done at 11.2 AFR on straight 93 pump. Timing is so low that even at 14-15psi it's only making 400-415 AWHP, and those runs are quiet until 7K.
