Thrilled with my Trinity
I would definitely recommend this tuner/programmer to any car enthusiast that is looking to improve performance in their car. I will say that the canned tunes (the ones that are preloaded on the Trinity) did improve my car (Jeep SRT), but nothing like a custom tune that you can get from someone who knows what they are doing or one you can get when dynoing your car. The interface and software was really easy to use as well as the logging for the custom tuner.
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.
