Mods to Ford Diesel

[Sourdough]

I met a man today that was driving an late model F-250 with the same diesel engine as my 2003 F-350.  He had done mods to his engine and was claiming 27 miles to the gallon.  First he changed his air intake system, got that from Ford.  Then he changed a chip in his computer, ordered that from somewhere else. he could not remember the source.  Last he had changed his exhaust system.  Before the mod he was getting 12 and 13 MPG.  After he gets 23 city 27 highway.

Any one know about this?

I checked on these mods for my Duramax. Since I get a lot better mileage than 12 to 13 I decided I would never drive it long enough to pay for the mods.

a chip helped my Cummins but only 2-3 mpg

Sure I believe that doubling one's gas mileage is no big feat. Oh and by the way I have some ocean front property down in AZ I really need to move quickly so can let you have it at a real bargain rat now iffen you'd like to snap up a real deal real fast.

I know you can pick up 3-4 MPG with computer and other mods together, but there is no way you are going to pick up 13 MPG... Someone is feeding you a line of bullhockey....

I agree with Graybeard and DirtyHarry(awesome movie!), if there was such a thing we would all know about it and have done it! My 2005 Dodge gets 20MPG on the highway in the summer and about 18MPG Winter highway @ 70-75MPH. It will get 22MPG @ 60MPH. That's with 3.73 gears and 285 tires. The guys I hear getting 22MPG etc. @75MPH are running 3.54 gears at least in the Dodges I know of. I have buddies with the Ford and Chevy diesels and the best either gets in Summer is 16-18MPG highway. We took my buddies Ford 6.0 to South Dakota with a triple axle trailer out to the hills and it averaged 8MPG! Cost us $800 in fuel! Could have left the trailer home and stayed in a cabin cheaper!!

My Chevrolet Avalanche gets about 14 - 16 mpg on an average trip. 

Maybe as low as 12 mpg around town.

It goes down between 5 and 8 mpg towing my trailer or in 4 wheel drive.

It has P 265 70 17 inch tires on it and 373 gears and an over drive transmission - that was just rebuilt last year.

I could do some more performance modifications - other than taking the guts out of both cats and probably squeeze 1 or 2 more miles per a gallon.  But that is about it.

The diesel modification is no longer a chip modification - people are feeding u a line of bull and you believe them.

What you can do is buy a module off Predator Performance that is driver tune able that will help you make minor modifications to your fuel and horsepower which will help or hurt your performance - depending on how much power and speed you would like out of your vehicle.

Intake kits and replacement exhaust kits will help the performance of your truck, but you can easily spend $3000 on these modifications and with the price of fuel - it would take you a long time to justify it - even if you saved 3 miles per a gallon and drove 15,000 miles per a year.

 The best thing to do is keep it stock. I have tried everything from a Hypertech chip, and mpg went down, slick 50, platinum plugs, fuel additives and it won't help mpg unless you have dirty injectors and put cleaner in once in a while. I checked my mpg with a gps and it did not help at all.

My dad has a 93 f-350 with a 7.3 that he uses to pull a 25 ft. gooseneck loaded with tractors and farm equipment. He noticed that it had lost a considerable amount of torque, so he had the injector pump worked on. It comes with a plastic fan-like blade inside from the factory, he replaced it with a metal one and put better injectors in it. It has almost 150,000 miles on it and after he had it worked on he said that it was almost as good as new. It helped torque, horsepower and gas mileage considerably.
