At first they gave the offical party line, but then said that they would cover anything that would not hurt the vehicle. The only thing is with the 2010's you must have a tuner to delete these codes which they say that they can see as the 2010's have a much more "elaborate" PCM, and in the event that a major component fails (block, injector, PCM) they are required to send in the latest program in the PCM. In order to do the deletes I want I have to have a tuner for the 2010 as they will not accept the standard 330ohm resistor sims and require a more digital signal to be happy. The H&S tuner turns off the regen cycle as well as the EGR so the computer is happy with healthy MPG gains at the same time. The H&S tuner also has the option to restore the factory flash into the PCM for service trips to the dealer, as well as emmissions intact tunes. I work on cummins engines everyday at work and I know the risk I may be taking but I also know the risk is small that I will have a component failure that will cause me any grief. I also am a responsible owner that drives with moderation and not WOT runs like most of the diesel guys here with black smoke pouring out the tailpipe. I want higher MPG and black smoke is un burnt fuel.
The EGR delete does not hurt the vehicle or cause any fault in the vehicle, removing it increases fuel mileage as well as oil service intervals amd engine longevity by not putting soot filled exhaust back into the engine.
The DPF delete will also reduce fuel mileage and increase engine longevity by not adding fuel on the exhaust stroke to the cylinder to later be burned by the DPF filter, which can wash your cyclinder walls and increase fuel levels in your oil.
These 2 deletes must be done together to prevent any issues.
