cummins 12 valve fuel plate
#14
i seem to have the same problem pulling hills empty at a altitude of 3500 to 4000 ft. 900 to 1200 degrees going 65 in o/d. if i have o/d off it is around 800 to 900 going 55. i guess the air is less dense that high up. i wonder what others are running at in mountain passes. in the flats it is 700 to 800 going 70 to 75.
