    My truck gets extremely short on power at elevation. The pyrometer on the turbo reads fine,all gages are in normal parameters the truck just gets sick but will hold climbing ability when cruise is on. When I get down to near normal elevation"truck is from ky" it runs strong and normal again. Do I have a bad sensor?

    Waiting to listen some good answers. I am on the same boat. My truck is a former Averitt MBE 435.

    Mine used to do it too. Perfectly normal I found out. Hell even my current 515 S60 truck does it to a certain extent in Wyoming especially.
