I have spoken to Will to set up an appointment to reflash my PCM with overkill. Will actually test drives your car and reflashes the PCM with a laptop without having to touch my PCM. My 02 GT has been running excellent after installing my k&n intake kit. The car is much more responsive and has more power than before, the shifting seems to be perfect now. I am wondering what this Overkill PCM can really do for me because of that. I am hoping I will get some extra horse power out of it mainly. I am currently running regular 87 octane in my car and it runs great. I realize this overkill pcm needs 91 octane or higher. I am willing to pay for premium fuel as long as this PCM really improves my car. Is the reason for the higher octane because the compression ratio is increased? Let me know what you think. Thanks
