I have a friend who told me recently that he bought a performance chip that plugs right into his boxter's obdII port. He has been raving about this little chip and said he paid under $60.00 for it. He and I yesterday tested car, seat of the pants test yesterday with chip in and without. I will tell you that the car seems to shift smoother and is a little more brisk off the line. He has a tiptronic trans. What do you guys think? Ger.
