I have a 2008 f250 4x4 crewcab w a 5.4L.. 8" fabtech lift...stock rims.. I get about 9.4 MPG not pulling anything.. I am also looking to pep it up a little bit, nothing special but so far only intake I have found is by AiRaid and K&N. K&N just being the filter replacement and AiRaid being the "Cold Air" intake

other than that I have thought about exhaust and a programmer, not sure on using the programmer with my warranty though.. I am not trying to make my truck fast but I know its possible to atleast get it running better than it is, I cant believe they wouldent have more performance products for a truck with the "smallest" engine in its class.. you would think everyone with one would be doing the same and trying to make it just a little bit stronger since it does lack for the trucks size....
