i just put the h&s egr/cooler delete on my 6.7 along with a mbrp straight pipe from the turbo back. im using a edge race juice with attitude to clear the codes. ive had it on level 3 and before i put the egr delete on it would smoke while i barely got in the throttle. now i dont have any exhaust smoke coming out at all? could this be a problem i need to be worried about, and is there any way to clear the egr/cooler codes permanently with the edge or do you have to clear them every time you start the truck.
