I bought this tuner hoping to gain some mileage and a little performance for my 2001 Ram 1500 with the 5.2 V8 mag. I went from a little less than 12mpg to sometimes over 15 which is a great gain. 50+ miles per tank. I noticed better throttle response as well. Also it's easy to use and loads tunes in a few minutes.
