Has Anyone had any experience with these when used for the LLY engine? Any feedback, good or bad, would be appreciated. Thanks.

I had one that I played with for about a week, it ran great, lots of torque, and i didnt have any problems with it. I sold it (in process) only because i already had a bully dog tuner, and have the TTS Tow Tune on a seperate PCM, so i figured i didnt need that one.. I bought it to really just test the unit out for myself so i could no a little - but i wanted to test it out so i could offer some knowledge about it and know a little more for myself as well

I run the hypertech on stage 2 with a 4" cat back exhaust installed by a local muffler shop. I went from 13 mpg to 15.7 mpg and have plenty of towing power, the trans doesnt overheat and very little exhaust noise. I run 285 16 bfg mud terrains. Stage 3 of the hyper tech make the tranmission slip when you get on it. Stage 2 seems to handle just fine.

Thanks for your replies, keep em coming. This site is great for finding out info and sharing experiences.
