i added a t s chip, 4position, 6 setting, and immediately improved my CITY mileage from 13.8 to 25.1 mpg........ better than any vehicle i have ever owned. to be honest, you have to drive it like a limo, not like a hot rod, but it rides great, and has dropped my fuel costs per week over $40. from the gasoline expedition (4.6 engine) that i replaced. plenty of room, excellent ride, and huge fuel savings, while also polluting about 70% less.
Ford really messed up when they stopped making the 7.3, and messed up even more when they discontinued the excursion. It is a great ride. i asked knowledgeable people before i bought, and looked for 6 months before i found the right one. certainly was worth the wait.
