Guess nobody has! I will tell you that I have tried it on my 2002 Dodge Cummins. From what I hear, the Hyperpac by Hypertech has some of the best tuning out there as far as being safe for your vehicle. I never got any crazy horsepower out of it. It is more for the guy that just wants a little added power for towing, economy and all around healthier performance. Definitely go with something else if you plan to race your truck.
The HyperPac is also probably one of the easiest programmer/chips I've ever installed.
Hope this helps,
