I have the 5.4 F250 4x4. I drive about 120 or so miles a day on the interstate (90%) I do tow a flats boat and ATV but thats about it. A large center console boat now and then. My question to you guys is what gas milage are the diesel trucks getting on the open highway running in the 75 MPH range. I seem to stay around 13.1 no matter what I do.
Second is if I bought a diesel and put one of the "chips" in it and set it to economy mode what kinda MPG would I see given the above speed. '
Thanks for any help for first timer.

Welcome to FTE.
It depends on what year you are talking about, and what truck you are talking about also. CC, SC, C, 4x4, dually. Answer these questions and we can give you a better answer.

A simple way to increase fuel mileage is to slow down a bit. I just drove from central Wi to central MI this week, 60-65 MPH and got 16.1 MPG. Next tankful was 70 MPH into a headwind for 150 miles, mileage dropped to 13.9 MPG.

Ok I know the slow down part but you get run over if you run below 70MPH on I 95 in Georgia. I drive this ride 5 days a week and want to get it over with.
I have a 2004 F250 Short bed 4x4. 5.4L Gas.
What is the best F250 4x4 to have for hwy MPG with or with out a "chip"?

Yeah, that & what weight you towing? Do you need a cc if you have one? I would personally get the smallest truck I needed & still be able to pull the load & haul the family. Sometimes though that means you do need a gas hog vehicle. I went with getting me an old ford & a minivan (5 kids. 4 still at home). I want a cc truck. I will get one soon. I'm looking now. I dont know what gear ratios they make for the superduty's but it might make sense for you to raise your ratio to the lower 3's. Then you keep your truck & save money not having to trade. good luck.

Well if I could get around 20 with a chip programmed on econ that would save me about $200 a month as it stands now. I have looked at smaller trucks but do not have the room I need. Thanks for the advise so far.

First rule of towing, screw what's behind you! No one is going to run you over. You may get flipped off or get and angry fist shaken at you, but slowing down 5 MPH isn't a big deal. Over 60 miles it will mean you get to your destination about 4 minutes later.

A diesel will almost always get better mileage than a gasser in the same vehicle, even if the gasser is a smaller displacement.... the BSFC of a diesel is lower than a gasser, so it will burn less fuel when putting out the same horsepower.
As to the chips.... their claim to fame is burning more fuel and smoking the tires. Hit any of the chip sellers square in the face with "What kind of mileage increase will I get without changing my driving style?" and you'll get hemming and hawing, and they'll talk about a "possible" increase in mileage, but guarantee nothing.
I have one friend with a GM and a 3-position switch selectable chip (don't know the brand); the "economy" setting gets the same as stock. Another friend with a Dodge/Cummins had his reflashed for economy, and his mileage dropped about 1 mpg... set it back to stock and the mileage came back up to where it was.
Just like the others said... drop your speed by 5mph and it makes a big difference in mileage. Remember... the Super Duty is:
a) Huge
b) About as aerodynamic as a brick

Don't chip your diesel. For proof, go search the 6.0 Forum for all the guys who regret putting in anything but a Spartan. And don't buy a diesel for the gas milage either. I get 18-20 on the highway going 65, but only 13ish goin 80, and 13-14 in town. Get the diesel for towing heavy, stay with your gas if it does what you need it to already.
120 miles a day: buy a used Honda that gets 30 mpg, or drive a truck that gets 14 @75 and suck it up.
