We have not had very good luck with our 2007 6.7 cummins. We have had a lot of trouble from the particle filter. With my experience with diesels if it doesn't smoke something is wrong. Cannot make this truck smoke. Every 12,000 miles we have to have the particle filters cleaned. They say it is impossible to put a aftermarket chip in it. What you buy is what you get. Hope things level out on repairs.
Good looking truck. Strong as an OX.
Put a different particle filter so it doesn't stop up every 12,000 miles. Make it aftermarket friendly, motor wise.
