I bought it to use on both truck with superchips go two purchase option. Also bought it for tire size and to turn off the active fuel management which it does perfectly. It is nice to have a 6th gear to use without having it go into 4cyl. mode. Seems to get better mileage because of the 6th gear. I only ran manual 5th because I didn't want it to go into 4cyl. I am happy with the performance gain. It is slight but noticeable and the shift setting options make it shift firmer.
