I have replaced every part of the after treatment chasing codes

Customer Question

I have replaced every part of the after treatment chasing codes that say the exhaust is still to dirty or that the system is regening to much. The catalyst would get a face plug on it so recently i replaced it also. Have had the valve seals replaced, injectors replaced, Turbo only has 100k miles on it. Truck is not really using oil or Antifreeze. Truck has ISX15 425st motor and is in a 2011 387 peterbilt
