Fuel Mileage question
I'm running a 04 250 CC FX4 Lariat 6.0 backed by a 5 speed auto and 3.73 rear gears. What kind of fuel mileage should I be getting? Right now I'm pulling down around 14.8 HWY. Is this optimum? Is there a flash out there that would increase it? If not does anyone run an aftermarket chip or retuner that would raise my fuel mileage? Thanks.

The truch is fairly new. I put 1,200 miles on it. Build date of 12/03 I also have an o4 F550 6.0 with a 6 speed manual. It has a Maintainer body on it. It weighs about 19,500#. It has 17,000 miles on it. I've never checked the MPG on it. It seems pointless to me since it runs from 6am to 6pm and I put roughly 200 miles a day on it. It'll use about 16 gallons a day. It's build date is 06/03.

My '04 350/3.73 gets 16 +/- most of the time empty, about 10-12 while towing.
MPG goes down rapidly when running above 2000rpm. Posted 19.8 on computer coming back from Houston yesterday--had a good tailwind. As I saw the mpg going up from a start of 17 at fillup, I tried real hard to get to 20, but couldn't, no matter if I dropped to 55mph.
