I seen a spartan tuned lifted cc/sb F-250 run a 13.2 in the quater with the spartan 275 tune :f:

The new 6.7 Cummins isn't all that much better. The LMM Duramax is a little better. the regen on all these new diesels is what is killing the mileage.

HI DANNY, I'm not a boy racer, THANKS for the advice, I need more MPG !!! I want at least 16 MPG in the city and 19 MPG in the highway

I almost bought the DODGE, But liked the FORD body better, and I was told the FORD frame is stronger, FORD interior looks better. But I want more MPG !!!

I was getting about 11-12 average mostly city driving w/ 35 x12.5 Mudgraplers.

The only guy I talked to that got better mpg without a warranty issue put a topper on his truck. It didnt go up much maybe 1-2 mpg. And YMMOT is right the Cummins isnt getting much better. My brother has an 08 6.7 and averages 16-17 mostly highway with the skinny a$$ 17's they put on there stock. And he has a perma check engine light that Dodge cant figure out.

I wish there was something else I could tell you, but it looks like you just might have to get used to it. Maybe when that warranty runs out you can come over to the dark side.

And that lifted 6.4 has 10'' of lift on 38" tires. Its a daily driver work truck that also won the work stock class sled pull the same day it ran 13.2 at the diesel nats in Houston.

That is the second one that I know of that has the forever check engine light.

A tuner software that does away with the regen and deleteing the DPF is THE only way you are going to get the mileage you want.

The frame on the 08 trucks is almost as stout as the 04 F450 frame. So yes, the ford frame is stronger. You also have to realize that the Ford is about the heaviest truck out there. Same cab config in Dodge and GM/Chevy is lighter. Heavier = hurting fuel economy.

yeah i pulled 2nd place behind him

congrats :5:

I should have been there. Oh well maybe next year.

In MIAMI, FLORIDA we don't have emission testing on cars or trucks !!! If I wouldn't lose my 5 years/100,000 miles warranty I would have pulled all that junk off by now !!!!

Ok... just was letting you know that any of the programmers out there will be a waste to purchase for economy unless you do away with the DPF and the Regen cycles. So if you don't want to do those two, then save your money until you are ready to do away with them.

HI YMMOT, I thank you for the advice, I want to remove all that junk, BUT I don't want to lose my warranty, I don't know how good these 6.4PSD are ???? I don't want it to break, AND I get stuck with the BILL !!!!
