I’m not too tech savvy, but I monitored Insite the other day while I was driving, and it kept putting the truck in high altitude derate. The turbo intake air temp sensor is showing a constant 118 degrees Fahrenheit. Calculated exhaust gas temp went up to 1600 degrees, but my physical pyro didn’t go over nine…I noticed on very hot days the truck performed a lot better. Also, when I try to do the injector check valve test on Insite it says it can’t do the test due to fuel pressure sensor out of range. Any ideas?

have you had the de-mandate programming checked/reviewed?.
