sorry to hear that man, i had a helluva time getting this manifold gasket today and it didint do what i wanted it to. Its not tuned at all, what exactly could someone "Tune". B&M adjustable fuel regulator aslo. HELP!!!!!!! I know this is gonna sound ricer as hell, but they said Stage 3 Camshafts. thats not why i bought em believe me. How bad is this exhaust manifold hurting me?? well i was at the dyno at J&J. It said i was putting 129 to the wheels. thats not what i thought it was gonna be. Dude you are putting down that little power with that much done. no offense, just cant believe it.
