I have a 2000 Pontiac Grand Prix GTP. I was wondering if you can buy a superchip for it to increase gas mileage/horsepower. If so, could you please name the place or the site where you can order it.

My best reccomendation is the Pontiac Grand Prix Club web site and SLP engineering also afterthoughtsauto.com. Several years ago the only way was send off your computer and have it reprogramed A set of SLP headers Random technology cat converter 3.25 inch supercharger pulley good cat back exhaust system. Then you will be looking for larger brake set ups.
