hahahahahaha i like the way you think! :thumbsup: :rofthey are full of $hit about the EGR and cat. 04 and newer had a cat, and the 6.7L started the EGR. as for passing emissions, its easy as pie. turn your box down and do the dumb snap test then soon as you go to pull out and leave with your pass paper, crank the chip up and black the place out!
