Been lurking here and few other places for awhile now and I'm looking at deleting my dpf. I know h&s and spartan seem to be the main two but I'm not looking for a horsepower gain. I would just like to be able to run an exhaust kit and maybe block my egr. Does anyone know anything about the dpf-r from gearbox or has anyone used it? It says it has a stock tune that deletes the dpf. Just curious if this would be a good way to delete the dpf without dropping $1500
