Diablo is a great tuner with a proven track record. You never go wrong with them. Plus AutoAnything was the only site offering a discount.

Got this to help improve gas mileage for a F250. So far I still get the same gas millage as before I install it. I have driven about 300 miles wit no change. Pulling camper this weekend hopefully it help with this. If not it was a waste on money
