Whats a good tuner to buy for a Series III 3.8 supercharger. I have an 07 Grand Prix GT. I've been wanting to get a tuner and custom tune my car myself but can't find one to support the PCM in my vehicle.

HP Tuners supports it all IIRC...if you buy the tuner you can tune at will with it, but I think you have a have a '05 PCM or something like that...I can't remember what it is with the newer cars but they don't like tunes.Originally Posted by JGT010
