If you still have a warranty I would replace it. Even if you delete it, at least you know you have a good working EGR to put back on if need be.

Yes I switched it back right away to the dpf present tunes... When I got home last night I loaded the oem tune ill see what happens with oem tune today... When I take it in to the dealer do you think they're going to hassle me because of it being deleted?

Same issue. I ran the mini max and dpf delete for about 9 months on the 275 tune. Yesterday, I put the dpf back on and and returned the truck to oem tune. Now I am throwing a code p0404. Is it OK to drive? If the truck has less then 100k on it, will ford fix it under warranty?
