Have you ever changed the IMAP and exhaust backpressure sensor? How about the delta-p sensors and piping? Cummins used to recommend pulling and cleaning the dpf every 250k but I think on the 2250 they upped that to 500k....just something to consider. If you pull it and walk it into Cummins they will only charge you around $450 to clean it.

Yes I've change out the imap sensor the pressure sensor and the temp sensor and have taking the exhaust transfer tube and the exhaust transfer connection tube off in clean them have not got to the delta-p or anything that far back yet..have a 2350 in Cummins saying 500k on the dpf but yes the dpf in on my next list of thing to do

try some penetrating oil and heat on the bung. try not to break the wires as you most likely have a core charge.

Some take 30 minutes some take an hour or more. It depends on how much soot is in the can
