According to the manual, at 10,000 ft with 14,200 RPM, the fuel flow should be 2700 lbs/hr. However, I am seeing only 550 lbs/hr per engine (so 1100 lbs/hr in total). See picture below. Some suggest this might have to do with the units in the sim, as the expected 1350 lbs/hr per engine are appr 600 kg/hr (which is much closer to what is shown).

I have created a seperate thread to allow discussion of this specific issue only. 

I am not the person who posted it, but this post over on the MSFS forums seems like it might be very important for ini to review and check. It seems like there might be a units of measurement conversion error at play with the fuel flow based on what this person found.
