It did exactly what I expected. This is not a device that is going to completely transform your vehicle. I upgraded my tires to 33" x 12" wide. By doing this, my truck lost some power. I bought the Hypertech for 3 reasons. 1) Turn off AFM. 2) Re-calibrate my speedo. 3) Pick up power I lost due to larger tires. It did all 3 just as I had hoped. It runs slightly better than when I had stock tires, so I'm pretty happy about that. With realistic expectations, this product is a great value!
