I have a 2007 3500 6.7 TD Laramie mega cab. Check engine light comes on here and there. Maybe a slight loss of power. Looking for a dpf and egr delete kit. Also a good chip. I regularly tow a 29 ft 5th wheel and drive long distances to work without camper. Aftermarket cold air intake on truck, no other mods. Any help or direction would he awesome.
