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.

2014 GMC Sierra 1500. Fairly easy installation. Manual days you need to remove several fuses, but this is not necessary. Just make sure headlights are off, radio is off, and nothing is plugged into DC outlets. Did what it said!
