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.

Plugs? Gap?
Gone, but not forgotten!
If I remember correctly they are gapped to .035?? Whatever is specified for the STS kit. They are the stock plugs.

X5 !!! Change them ASAP
I just did. The plugs in the pics were the stock ones that came out. Didn't help any since I think my injectors may be maxed.

If they are stock plugs I'd try swapping them out for some colder ones. Try the NGK TR6.
Other than that, there shouldn't be any reason for it to knock if the meth was working correctly. Might try turning it up a little bit to spray more.

Yeah, I was running .028 @ 10 psi.
Change the plugs & try again.
