Sounds like your truck isnt completing its full regeneration process. Are you doing short trips and in town driving. If you do lots of short trips or city driving it will keep in regen trying to burn out the dpf. But in town its not getting the egts hot enuf to burn it out and it keeps building up with soot.

And if you do short trips and dont finish the regen cycle it will go into regen every start up waiting for a long drive to clean out the system. Regeneration takes around 20 minutes of highway driving to clean it out and finish.

Also some 6.7s had some troubles with dpf system and needed a new flash to fix it.
