Uprev can tune the Stillen kit to a degree. I have three maps for my truck.

I wish it were the rear belt. My jack shaft is not 100% perpendicular to the front serpentine belt, and it causes a very slight misalignment where the belt rolls off the jackshaft pulley and onto the first SC idler pulley. Its worse in the winter, but even then it goes away after about 4 or 5 miles. If I am not mistaken, the only tuning you did with your Uprev was to remove some limitations put in by the ECU, like WOT, Top Speed, Rev Limiter. I considered Uprev as an option recently, but decided if I want to go balls to the wall fast, I will do it in my car. Not having the top speed/rev limiter removed did affect my ability to dyno to its maximum though, kept pegging it out in 3rd gear. I am satisfied though. I bet your truck would love the dyno now. Would be nice if Uprev and Stillen had some partnership going, and the need for the extra 8 injectors and piggyback were gone, but business is business, and hopefully all us enthusiasts benefit from the competetion in the long run.
