I installed the Unichip on a 2003 Toyota Tundra. I have a K&N FIPK and Cat-back exhaust system with the flowmaster 80 series muffler. For those who are thinking about getting this, get it. It gave my truck the performance boost that I was expecting with the FIPK and Cat-back. The agressive settings recommend you run 91 grade fuel, but I was doing that anyways. I haven't test MPG yet but I'm expecting better mileage because I don't have to downshift as often. Very happy with this install.
