just wondering if anybody has herd of anybody working on making pcm's for the 06' and newer grandprix. I would like to do alot more to this car but I want a dyno tune if Im puting the money into it.
I want to say HPTuners does something with 06 PCMs. Not totally sure but it is something to look into. Especially if your gonna get that Regal and do some swapping and mods to it.
