You get the truck back, run multiple back to back oil changes, every 5000 miles or so, wash that soot out. And a good EGR tuneup. If you are keeping the emissions, like How said, get an Amsoil bypass filter and see if you can get a more owner friendly tune on the ECM to allow the emissions to work more efficiently. Or go the other route, and rid yourself of the EPA. With your truck it can be accomplished in your driveway with a laptop and inline 6 reader, along with some simple hand tools.
