thist is the 3rd Hypertech Programmer I have had and with no exception this is the best in performance fuel mileage. I bought for my 2006 GMC duramax 4X4. Has K&N filter, 4" exaust and oversized tires. The programer does everthing it said it will do - more fuel mileage, power and corrected my speedo to macth my tire size. Thanks Hypertech.
