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.

I have a DS Predator for my Hemi Dodge Magnum, which I've had since they came out, and now also the new one for my Hemi Jeep Grand Cherokee Overland. The newer one (Jeep) does not provide as much flexibility as the older unit. I don't know why they (DS folks) did this, unless it was to keep novices from ruining their vehicles. You no longer have options for torque management, tranmission settings or ESP/Traction Control adjustments as with the earlier model. Other than that the unit is about the same and is very good. It offers WOT fuel and WOT timing adjustments, modification of the stock tune, as well as throttle sensitivity adjustment settings. Since the throttle on my Jeep was very touchy, this is a great feature to "tone it down", and adjust it so it has a smoother, less jerky operation. The DS also offers a 93 octane tune, which the competing unit does not. Most other features are similar to the unit from their main competitor. Overall, between the two (I have them both for both vehicles) the Predator is the best bang for the buck, IMO.

Does what it's supposed to do.
