Worked out real well. Don't know about miles/gal (7.3 diesel) increase yet.

Installed and downloaded all in about 30 min. This thing gives sick horsepower in performance and extreme modes. I havent had it long enough to tell about mileage but it looks like it has come up a little. Cant wait to get a cold air on next!!
