What plugs/ gap/ size shot are you running? What plugs are you running, what are they gapped at, and what size shot are you running.
I'm running the ngk br7 non projected tip and am starting to think I might have them gapped to high. Out of the box they are set to like .28 and I took them up to .32.

TR7's gapped at around .028-.030
I believe you are supposed to drop the gap .005 for every +50HP. Since it's .060 gap at stock 300HP, +100HP for cam and bolt ons and +150 for the n2o means I should drop the gap to around .035. I gapped them at ~.030 so after a little use when they open up, they should be right around .032-.035. Plus I usually gap them lower singe my plug gauge is not very accurate.
