The Hypertech is a great tuner if you have different gears/tires etc... You can raise your speed or rev limiter too. Since none of this applied to me, basically all I had was the power programming itself. But the power programming didn't do any good for my car, at all. I actually lost gas mileage, and the more I read up on it I found out all the tuning does is advance timing which really isn't that great for the car.

So no gain in performance at all + worse gas mileage in all situations =

Oh, and if there are any misspellings here, don't care, broke my first 2 fingers on my left hand, so yea.
