    A couple racers tried it. They claimed it didn't do anything. I am running an 07 reflashed ecu in my 08 PX. Need to take it to the dealer for BUDS work. Mine needed some updates, reset, and match to the gauges and I was good to go.

    I know mitch411rxp tried a stock 07 ECU on his X. I think it worked, but I don't think he gained anything.

    Wouldn't it run lean with the xcharger and 42s?

    I have a 07 ECU you can try if you want. It would need a Key.

    Think it will be rich on bottom since it is setup for 38.
    It don't gain anything and you loose the presets for trim.
