I would put my vote in the ECUTEK reflash but I personally would hold off until Mastro figures out what they are doing with the whole dyno/ECUTEK setup they have going on. The stock ECU should be fine with most of those mod. My car seems to run a bit rich now with my mods on the OE ECU with after fires on quick shifts from 1st to 2nd and pops here and there when the engine is cold.

I've said it before but I'll say again to leave the intake and BOV off your mods list.
