    you could, but why? If you are running what you say you have in your sig, get real engine management, a pr4 map is not going to supply enough fuel to your turbo setup. Get your pm6 socketed and go download BRE or TurboEdit. You should really be using a more comprehensive tuning setup than you are. I predict a quick death for your engine if you go the pr4 route. Either buy the tuning tools and tune yourself, or get someone to tune for you. If you need any help with what to get tuning wise, post it up, I'm running obd0 with turboedit, and have done a bit of tuning.

    Just use the stock ecu, you'll just be adding more fuel that you don't need. Just reset the ecu by pulling the ecu's fuse and backup power, and then plug it back in and enjoy. A pr4 will do you more harm than good unless it has been chipped and tuned.
