I just got my truck reflashed, went home parked and hooked up my Edge insight monitor. The next day I left on a very long trip and as soon as I am on the highway at 70 mph the egt's go to 1050. It never ran that high before. It used to run about 700. Even when it goes into re-gen the temp doesn't go up now. Any ideas what is wrong or if I keep going am I doing harm to the engine. (Sorry about the re=post but I am nervous about harming the engine, thanks.
