Mountain Performance
After a wonderful weekend in Steamboat we were returning to Denver. Coming up one of the steeper areas I had this "issue".
65 Mph, 4th gear approx 3k rpm. Pedal on the floor. Slowly losing speed. Boost gauge never went past 50%, approx 20 psi.
Dealer said it was because the last regen did not complete and charged me to do a manual regen.
I have not picked the truck up yet to see if that made any difference.
He said they don't have any hills around and do not have a trailer so they could not duplicate the symptom.
My question is- What amounts of boost are you guys seeing when pulling hard?
Trailer is a 42' Fiver approx 16k.
Oh, yeah. 2017 F350 dually, 4.10 gears.
Seems to me if 20 psi is max they would have calibrated the gauge to show the same, therefore I should be able to show at least 75% when full boost?
Everything is stock. New(er) air filter, nice and clean. Newer fuel filters.
Thanks for your input.
Other than that no troubles except the damn traffic!

We have basically the same units (truck and fifth) but as I've never pulled outside of the souths flat-lands I can't answer you.
My troubles? In Sep 2017 we passed thru the same area (Honda van) in a snow flurry, all I had was summertime shorts. Going back this coming Oct and will be better prepared.
