I don't have a Duramax, but I have a 08 Dodge 6.7 Cummins Diesel and it's already at the Dodge doctor cause of the engine check light and the DPF crap they put on it. Also the catalyct converter came out to be bad. What a disgrace. I Should've gotten the old 5.9 Cummins engine. At least they don't have all that epa/dpf crap.
