2 Mods huh? lol, I x2 this guy's recommendation. I had the exact same problem when I installed Stage 2. Changed evrything out, coils, plugs, gaps on plugs changed, nothing, car would get to about 5800, and it would happen! Iridiums suck! lol ONLY reason why I say this is because THIS WAS my problem. Installed silver plugs, and now I run all the way up to 6500rpms, no issues. Same gap, only changed the plugs. Hope this helps, for all you iridium users. J/K
