Sounds like who ever did the orginal work messed up in the programing. Never heard of the problem you are having, my J35 on my 07 had no problems. Time to take all documents related to this problem and find a different dealer who has a cummins tech person or at least call the zone rep. At only 68,000 miles are you not still under warrantee?

Just wanted to update I got my truck back today and the dealer told me the cause of the trouble was the new #5 injector they installed was faulty and alowing the rail pressure to drop to 2000 psi i have only put 25 miles on it but it seems to be fine
