very easy to use, power gains are very good and better shifting from the transmission. It is worth every penny.

The diablo tune on this tuner along with transmission hard shift tune works amazing, with it on Diablo tune I saw a mpg increase of about to 1.6 mpg. I am burning straight E85, now i get my normal fuel economy while burning E85 that only costs me $1.59 vs $2.59 a gallon. The pickup drives much better and stays in a higher gear while driving because it now has a lot more power to pull the hills. Only complaint is having to update the tuner when you get it which should already be done for you IMO
