Overall, I am satisfied. However, I am a novice at modifications, so adjusting the shift points was a bit tricky. I did not get the real fuel milage gains that I thought I would get. But, I did get some improvement with power gains. I would say that this product combined with other power gaining products would be great. I am satisfied with the product and I am glad that I got it. I look forward to its proformance when I continue to modify the truck.

If getting your speedometer to read correctly after changing to larger tires is a must, like it is for me, than this is the right tool. Just be prepared to make multiple adjustments. I'm running 35" tires and played around with the tire size setting until the calibration thinks I'm running 33.25" tires. In the end I don't care what the calibration thinks I'm running as long as the speedometer is dead on.... and now it is. So I recommend this highly just be prepared to make a lot of adjustments.
