got a 07.5 6.7 that came in with a smarty on it and it didn't return to stock correctly so I don't have a usable stock file that is clean and the same os current os is a 11551035 can I switch it to a 11620807 and be ok? truck was a 08 I read out and it had a clean file and optioned similar mega cab with leather? never done os swaps with cummins so don't know if it is a big no no or not
