Ok my father in law has a 07.5 c&c 6.7. Hes got the deletes and an mp-8 and xrt. He went for an inspection sticker with the XRT on and he failed for the egr and catalyst not being ready to test. I was under the impression the XRT was to allow you to have no lights on so you could get a sticker. To make a long story short he ended up plugging the egr back in and taking everything out, reseting the computer and driving around for 125 miles with no codes thrown to get one. I have an updated flash on mine and throw codes with the sims in and the egr plugged in. I get 8-13 codes everytime I scan it. What am I supposed to do about a sticker If I cant get one with the XRT on...
