Cm2250 excessive regens

[Ironhead]

So after 170,000 miles after my egr tune up and truck running great, it has started doing alot of regens and the light will stay off for about a mile then come right back on. When I had the dpf off and cleaned they said it was likely needed replaced. Plus my fuel mileage has dropped tremendously,I have insite and inline 5
I'm looking at doing a demandate when I get home was given a link to another forum but I dont really think it was a legitimate forum. Anyone close to north west Arkansas. I cant afford to be down or get mislead 6 kids and a wife already bleed me dry lol.
Thanks in advance mike
