Fuel Injection System Specifications NOTE: Engines may not reach rated full power RPM during ground run- up due to atmospheric, environmental, or configuration limitations. This condition is normal, occurring most often when operating naturally aspirated engines configured with a fixed pitch propeller. A correction factor must be applied to reduce the fuel pressure to the lower maximum RPM observed during fuel system adjustments on the ground.
