Well after I got my built trans in, I decided to go ahead and crank up the boost to 10 psi (was running 8 before). My AFR was still in the high 10's low 11's and I was only running 12-14 degrees of timing. Yet I was still getting 1-2 degrees of knock and could definitely hear it. Any ideas as to why that would be? Meth was working IAT's were in the 70's which was at or below ambient. Need some suggestions please.
