I know I know get a real tune and after reading on the site I probably will in the future a few things are higher on the list... But in the mean time I put the hypertech progamming for firmer shifts and removed the speed limit. Then I repogrammed my car with the diablo sport, using the stock tune again as above and also maxed out the shift firmess for all shifts, then programmed it in. They both work differently, I think the hyper tech uses the pressure solonoid and the diablosport prediator uses shift pressure tables to make them firmer. I was curious if it was bad to do both, some of the shifts in tow haul are pretty hard but that was with a heavy trailer on my 05 silverado. Just curious what people think, if I get the new tune and a few mods to the tranny I will get what I want and probably be better off, just have to wait for the funds to do it.
