Wow! It sounds like your setup is doing much better than mine. I got three different programs from Rick at STS and tried each of them again this weekend and adjusted shift firmness, quickness, axle ratio, etc. Still am not getting JACK for performance off the line. My Predator Diablo programmer didn't come with a program that would run the Hummer though. You could start it and it was extremely rich and sounded like it had a radical cam. Do you have the tune file you used accessible to where you could email it to me? Or did you just modify the tune delivered with the Predator. The shop that installed mine said the previous H2 they did with the same kit came with an STS program already installed, but mine didn't. It is getting very frustrating at this point and the shop that did the work is related to the family. Stuck between a rock and a hard place.
