does the dpf cause the new 6.7s to have bad gas mileage? i know its supposed to help emissions but it makes the truck quiet and it seems like the 5.9s get much better gas mileage?

Yes the DPF is part of the cause of poor Fuel Mileage.

No I disagree strongly. I just put the delete on my truck and I went from 12mpg to 17mpg. Someone has the wrong delete:butt:
You have read my statement wrong. The DPF is the Cause of poor mileage, the DPF Delete Improves Mileage.

:thumbsup

By the looks of your signature you have one. There are a lot of threads on this site which discuss what that is. This is a big one to know/learn about. It seems to be much of the cause of a lot of grief with the new 6.7. I have not had an issue yet but I pull a lot. Whatever the case I have not had any codes or DPF messages yet. :pray:

Dpf What's That?
You have one. It's a Diesel Particulate filter in the exhaust and it sucks.

I hate mine. And yes many of us are waiting for H and S fab to come out with a kit that don't trip codes to delete it. Just keep checking here, I am sure we will know when a Code Free Delete kit comes out. :)

The dpf is dodge personal f--up
Remember, Ford and GM use DPF's too so this isn't just a Dodge issue. Go read the Ford & GM forums and you will see the same discussions about poor fuel mileage and deleting DPF's.

not just pickups, either. OTR trucks are getting DPFs as well.
