could be turbo.. could be valve guide seals.. could be seeping egr cooler, could be a lot of things.

Also.. if it is de-mandated.. assume the program is bad and harmful to the engine internally until you get it properly reviewed.

Copy the program out of the ecm and e-mail it to me for a proper review to ensure you did not just trade away DPF problems with severely shortened engine life... all while swearing that it seems to run ok.
