Short but sweet
I had a little bit of difficulty with the initial download but the patient, friendly and knowledgeable operators are only a call away during business hours. The guy walked me through the entire process in no time. Installation wasn't too bad but they could use a better piggyback for the fuse. Buy one, you'll see. I erased the engine code caused periodically by my cold air intake, raised the speed limiter and raised my shift rpm's in minutes. I got T-boned that day so performance? Not sure yet.
If it says saves on fuel mileage there wrong. I get about the same but the performance part is nice power and speed throddle response is quick. Have yet to haul or tow anything yet but main reason I got it was for the economy part maybe I need to screw with it more and find what works best cause they don't give you a manual on how to really tune it. All and all not a bad purchase.
