those diablo sport tuners are all pretty much the same thing. they have pre packaged tunes that are supposed to work on a variety of vehicles. they do not have the parameters built in to make custom adjustments and to take scans to see how your car is actually reacting to the changes. what you need to do is find someone local that can do the tuning. I wouldn't waste your time and effort on a tuner unless it is an hp tuner, or finding someone that has one that can do the tune for you.
