I just bought a Phantom Metallic Black 6 speed '05 GTO and let me tell you...it is one hell of a car. I want to do a couple things to it to make it faster, but I have not seen any performance parts online. I don't know much about cars, but I am hoping there are some easy things I can have done to give it some extra juice. i don't want an exhaust because the stock one is sweet enough....NOS is out of the question....and I am not supercharging it because of the price...so what can I do? I have not seen any engine mod reprogrammers (place site to purchase here...) out for the '05 yet. Let me know how to maximize power, torque and HP. I want to create a rocket!!
