I bought my truck used and knew nothing about the "economy" shift to 4 cylinders. My truck did it like crazy and I thought my transmission was broken. Did some research and found this product. Works as advertised. And I like it.

I used the 91 octane program and I can tell the difference in acceleration and I don't have to get on it as much to keep up with traffic. Took 10 minutes to install and you can update it online.
