"Installed the Chip about 2 weeks ago onto my 3.4L Tacoma that already has Cat-Back Exhaust, Cold Air Intake, and Throttle Body Spacer. There was an instant change in sound, idle, and throttle response. The power is much smoother than it was before install, as in it is a much more constant pull throughout the RPM range. That being said, all the hype about improved gas mileage was not true for me. I had done several test runs setting the cruise at 65mph and running through a tank getting about 16.5mpg average. Now with the chip and premium fuel and the same runs at 65mph I'm only getting about 17.5mpg. Overall I would recommend the chip to anyone but don't expect big gains in fuel mileage." —Patrick M from Bowie, MD bought an Unichip Performance Chip for a 2003 Toyota Tacoma, 3.4L V6, no TRD Supercharger.
