Im just wondering what kind of boost and timing you guys still using pump gas are seeing. Ive been playing around more with tuning my own car.
I've noticed I start to get spikes in knock control at 5500rpm when running 24psi. The ignition table was calling for about 2* advance at this point without any adjustments. I tried lowering the timing to 0* and it does not knock as much but does not feel any faster either. I ended up running 23psi @ 0-1* then tapering off to 22psi by 5500rpm and advancing to 1.5-2* by redline. This seems like about all I can get out of the 93 octane without spikes up to .7 - .72 on knock control. Currently max knock control I see is .62ish.
What experience have you guys had with (safely) maxing ignition advance and boost level on pump?
