I posted this on the other forum, so here goes...
this was verified using a knockbox/headset + dyno , 93 octane, 26-27psi boost and a 2.2 with CR9.5
That is all the boost i ever plan on running with 93
There are peaks where it knocks on my motor
Mine was at 4500-5000 and at 6000-6500.
I'm sure every car will be quite different, but this is what worked for me
