Also, if you're having questions of knock, drop the boost to 10psi and see if it's still there. Granted the engine is less noisy when it's not making as much power, but this may shed some light. When I was having false knock, it would still show 1 counts with 10psi and 10.3:1 AFR. Definately not knock.
Just using the Gram 5.0 you can tell if it's knock or not conclusively. No need to guess.
I think I'm just going to make all 3 maps ultra conservative and go from there.
