It works likes its suppose to. Shuts off the AFM so the truck is always in 8 cyl mode. It has come loose a couple times though so the AFM kicks back in.

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!

This was pretty good programmer i could really tell the difference in acceleration and power. I have not had it long so still unsure of mpg gains but it seems like a tank of gas goes further than before. Was a bit expensive but at 20% off had to try it!
