First of all, like they said, it's most likely just a chip for the ECU, you'd still have to pay someone to solder in a socket to your ECU. That being said, you wouldn't see any gains from it, especially being auto. If I was you, I would spend the money on suspension. Get a decent set of springs and shocks, and some stickier tires. Unfortunately since you are automatic, on the go fast/horsepower side of performance you won't really see your full potential...but that doesn't mean you can't hang a corner with the best of them.
