Hell, as a 6.4 owner, I would entertain the idea of a UREA conversion if it even existed and it kept the warranty intact with Ford. We just don't have the money to throw the warranty out the window right now. And not that there's anything wrong with the truck right now, it runs great, but fuel dilution always leaves that little nervous tick in the back of my head. The mileage right now isn't bad either for what it is, but I'd take 6.7 mpg all day long if I could get it.

Maybe when the warranty runs out we'll look into a mild tune to ditch the DPF.
