I have a 2006 F-250 Diesil, crew cab, 2 wheel drive, automatic, 6.0. I have had the truck about a year now and it has 57K miles on it already, I do alot of freeway driving for work. I never tow anything and I don't drive it very aggressivly (well, maybe every once in a while), I went with a diesil for the engine longevity.

I bought the Bully Dog Power Pup downloader, and with it on the lowest setting my MPG went from 18 to 20. I have talked to a few shops aboutgetting a cold air induction kit and a 4 inch exhaust installed. One of them told me that if I do that, I "could" get around 25 MPH. I don't know the first thing about cars, trucks, engines, or any of that sort of stuff. Can someone tell me if 25 MPG sounds resonable? Also, if I have all of this done will there be any long term ill effects to the truck?

 

Buddy of mine hasa CTD with the BANKS system (i think), exhaust, as well as CAI. He gets around 24 so i'd say that is not too far off....
