Have a F-450 6.4. not a mechanic but try to do what I can to save money. I am driving the other day and am watching my tuner (edge) that I run on tune 2 when pulling my trailer. The EGT seems to be getting climbing small hills. I don't remember it doing this on the same hills before. Have checked the hot side bottom inter pooler hose and replace it. Still same problem. I am also watching the boost. It seems to go into the 20's and 30's on the same hills. Don't remember seeing that before. Any ideas on what to check? Reading some other post and they talk about cleaning your dpf pressure sensor? Can't even find this on ford parts site?
