Ive read alot about the problems with plugged DPTs and ruined turbos in the 07-08 model years. My question is has the problem been solved. I am considering purchasing a 2010 HD and I really dont want to have to make freeway runs on a regular basis to keep the emmisions hardware working. For the price they are asking for these trucks one should be able to baby the truck or run heavy and hard without worrying about what it will do to emissions components. thanks for any info.
