What are you running for plug gap? We always have to gap down to around .024 to get over 33-34 psi. That's always about when we see blow out start and a quick gap down on the dyno always clears it right up. .024 on stock iridiums let me go to 42 psi on that 6466 car recently. With .028 it started blowing out at 34.
