I just got an 2008 F350, and its averaging 13.1mpg and was wondering what I could get to get a good bit more mileage out of it? I know tuners, etc., but what brand, where, what all do i need? Not going to be much towing with this truck, just a daily driver.

Any help is appreciated!!

 

I have a H & S XRT PRO, with egr, cat, & dpf deletes, i'm getting 15 mpg city driving, but i'm racing it & driving my truck like i stole it

 

okay thanks!!

 

Unless you pony up the money for a DPF delete and a H&S or Spartan with the delete program your fuel mileage is NOT going to get much better. Diesels need to breathe and if they can not then the fuel milage and power goes down. In diesel motors when you increase power you increase MPG. If your cant fork over around $2000-$2500 for the DPF delete and a new tuner with a delete program then any tuner on the market is fine.

Another thing to make sure of is frequent oil changes. The 6.4 is horrible on oil and can drag MPGs down. Change both fuel filters and drain the fuel water separator. Most 6.4's get around 14-15 around town with stock components.
