2016 PX-9 Exh. gas pressure above max.

Always appreciate any help i receive. Dpf temps around 1000* + doc 700*. Did update the ecm with current calibrations. Ran test 4 times failed 3. I to just dont see another direction to go to. That why i put it out there to you guys who know and have more experience then me. Hate to have a trk come back after i worked on it. Thanks for the help

 

Yes I did clean the tube and put a new sensor on it to see if there was any changes there was not . I think I do remember seeing the gas pressure up around 137 . I'm sending it back Monday and let them use it see what happens . I guess I will need to check the turbo if it comes back. The trk only has 40,000 miles on it .
Thanks again for your time and help
