Having overspeed issues on my heli turbine rotor

So I’ve got props that are set at a rated speed of 225 and I can get them to spin at that speed with my N1 set at the correct rpm and percentage (if) I set my maximum torque much lower than it’s supposed to be. Am I missing some sort of governor setting?

If I set my maximum_torque to the appropriate values based on my SHP and N2 RPM, my rotor overspeeds by about 20%

It would be awesome to be able to assign the ratedRPM as well as spinUp, spinDown settings and have the sim change use the governor to achieve those based on selected N1 conditions.
