I had it in my truck for one day to try it, and it made no difference I removed it the next day. I have since reorder a Edge chip that works.

First off, this thing looks awesome. Much cooler than some of the other programmer modules. You can certainly feel the difference in power but in towing mode I'd guess it eats an extra 20% more gas than usual. In gas mileage mode I'd say you'll notice a difference of about 2% which isn't bad, I mainly bought this for towing and some added HPs. Overall, very happy with the unit.
