Looks great, does little
I had to buy a PC laptop to be able to download my car's programming data, which should have been in the Trinity from the beginning! It was supposed to be "customized" for my car, out of the box. Once programmed, the only difference I can discern is that my transmission is shift-happy. It quickly downshifts, then upshifts while I'm accelerating. I see absolutely no performance increase, and I feel I've wasted my money.
