Taken from the testimonials:
I needed my car to go faster and I didn’t want the mess of a supercharger or turbo. I picked up the RS4 chip and now I’m going faster than I ever thought possible with such a simple upgrade! Added exhaust and an intake and my power gains were even more! I’ve got one true racecar now!
