    so...is there a question here? you installed a "stage 1 PCM" and you're not happy with it.
    Have you done any of the supporting mods like CAI, pulley, exhaust?
    did you allow the new PCM to learn and adapt its trans shifting before going out and thrashing on it?
    did you do a crankshaft position learn to optimize timing?
