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.
