RE: Big Problem (ram 500)
If there is enough battery to start the engine, there wil probably be enough left to run at hi rpm if the fuel system is not clogged. The pump pw is calibrated to the current battery voltage at all times. If the fuel system is not clogged and the pump is ok, the pump pw at full power will be about 250-350. The maximum pump pw limit is set at 600 so there should be enough margin to run at max rpm if the battery is good enough to start the turbine. If the fuel system is not working correctly and the pump pw is running above 500 with a fully charged battery, the full rpm may not be reached with a low battery but 122k rpm seems low.
