Man I miss my 02 duramax... so here is my question. I have a 08 LMM I bought an afe intake and edge evolution. I am ordering an mbrp 4 inch dpf delete. Is there any options other than buying a new programmer that will keep my truck from throwing dpf codes?

yeah duramileage isnt worth the money, if all your looking for is mileage, the vendors have dpf delete kits available, give one of them a shout and they will set you up
