I was wondering how high of timing are you guying see on 93 Oct. with a 2.38", intake, no cats and stock cooling system. In the upper rpms (above 4400 rpm) I'm only able to get about 15* of timing. IATs are good (just above 100 degrees after the WOT pull). Current boost is about 15.5 psi. AFR is about 11.3 in these areas. thanks
