Well I have been tuning the a/f and ign on the z1 I just put in, but cannot seem to shake the knock occuring when I am at @ 3k and floor it. As I start to climb in rpm to about 4-4.5k the intake gets really loud and the knock begins registering. It happens in most gears and only when the intake is loud. I have innovatives also so the car gets pretty damn lively when it is in certain rpms with full throttle. Any suggestions? I'll post this datalog later, as the one I have is huge from trying to recreate this in many conditions.

It is possible, what intake are you using?

Have you tried adding fuel to reduce the knock, or only pulling timing?
