2006 F150 4x4. I purchased for gas milage boost and tire size change. Follow instructions and it is straight forward. You will need to download latest updates from the web before you start. I used the standard 87 tune. After running about 3 tanks of gas post tuning I have found no appreciable difference in gas milage - that was a disappointment. However, shift points are much smoother and truck runs much better - that was great.
