instead of buying a complete exhaust just straight pipe it, that will save you $$$ a superchips programmer isnt much for performance but its good for upping you mpg. adding an intake system will help out also. power service in the grey bottle is pretty good in boosting you mpg. you tires will only hurt your mpg in stop in go driving but when you get out on th road thay will lower your rpm's(almost acting like a set of hwy gears). but all in all if you had smaller tires it im sure it would help some.

Love my 37's for milage on the hwy.... Turnin 1700 at 68mph... Intake, Exhaust, Chip... Even some AC injectors might give you a mile or so per gallon more.

Hi.. I am new to here as well... got my 01 Ford F250 w/ 7.3L and loved it... when I do tow something I really don't notice something back there... but it's my daily driver and I travel 40 miles to work round trip... if I run only 60 I manage to get around 16 maybe 17 mpg... what can I do to better this... I have this Edge Evolution programmer that I run only in the performance mode if I want... I have thought about adding a tonneau cover and heard about openning up the air intake whole behind the grille helps... does it??? any help would be greatly appreciated... thanks

additives will give you 1 to 2 MPG:humm:

4.10 gears or something?

I'm turning about the same RPM's at the same speed on 315/70/17's. Going to a true 35x12.5x17 now. I love the 35's, my mileage has definitely improved, but I do mostly highway driving. I'd imagine around town this would drop it though.

The only way I know of this being even remotely possible, is Rev-X in a 6.0 that had sticky injectors.

Other than that, I don't see any oil or fuel additives actually increase mileage, and if it does, not by that much.

JMO.

Limit your idling, most guys I know let their diesel truck idle for no reason:argh:

looking for a new programmer... more toward the lines of economy then torque or stuff like that... any names of some would be great.... what is the thoughts on the second generation edge evolution programmer... i heard it will allow you to boost mpg and also be a display for your extra gauges.... any thoughts on that one

For a 7.3 I would get a TS or DP tuner, 6 position.
