There are threads talking about tuning here but they don't explain how to actually tune your car. If you buy the Trifecta tune you can download it to a laptop and apply to your car. If you buy the Bad News Racing (BNR) tune they offer a hand held tuner to apply the tune to your car.
With both of them you can also tune the transmission to shift better. You will have to run premium fuel with both tunes since the turbo produces more boost to give your car more power. Both tunes also give you the ability to change the tune back to the factory tune if you are taking your car to the dealer for warranty work.
