Great customer service!!!
I needed some modifications for a custom tune that I was unable to do myself. I called Extreme Motor Sports in Tempe, Az. Within a couple of hours of emailing my tune to them, they had made all the necessary changes and sent it back to me, free of charge! I uploaded it using the Ls1 edit to my car, it runs great and I passed dreaded emissions. Best of all no PCM codes (knock sensor) whatsoever. I'm very pleased and will always go back to Extreme Motor Sports for future mods!

of them to do that. I haven't had them do any work to my car, but I have bought things from them and always received first class service.
