    the PCM was already installed in the car when i bought it and the only thing i know about it is that it has been reprogrammed and the label says "REMANUFACTURED BY GM CORP. SERVICE NO.16236757"
    As in other mods i believe its got a 180F thermostat, a cold air intake and a 3.4" SC Pulley.
    I'll be getting rid of the cold air intake and will be putting on a intercooler to help the SC stay cold as on the PCM i'm not sure yet but i think i'm getting rid of it too.

    This is a remanufactured PCM, not reprogramed.

    This does not seem like an aftermarket tuner company to me. This could explain why you did not feel any difference in swapping the two PCM's.

    The label explains it, it states remanufactured, and not reprogrammed.

    Just my take on it...

    You have two PCM's for the car, one could be faulty.
