Well... For starters, you need a tuner. Or, you should by the chip from someone who's tuned your exact same setup and have them load that tune on your car. There is no way to tell how much you gain from the new chip. Do you have any more than exhaust and air filter done as mods? The chip replaces the stock chip in your computer that is located in front of the door to the right of the passenger side floor. The passenger could tap it with his / her right foot.
