Some 05-07 F-Super Duty vehicles equipped with the 6.0 diesel engine may exhibit reduced engine performance condition with no diagnostic trouble codes (dtcs) when operated above 5000 feet above sea level. This condition may effect 05-06 vehicles built before 03/15/06 that had a powertrain control module recalibration, and 06-07 vehicles built after 03/15/06. ACTION---reprogram the pcm to the latest calibration using IDS release IDS 47.3 and higher. This calibration is not included in the 07.1 dvd. Calibration files may also be obtained at www............com. (If I told you that, I'd have to kill you)
