As stated above, altering the fuel flow is the primary way of changing the RPM of a gas turbine. The fuel control unit and/or governor monitors various engine parameters and adjusts fuel flow to maintain desired RPM. These systems also compensate for changes in the atmospheric conditions such as air density, temperature and air pressure.

I saw someone mentioned in the thread that disabling direct mode in steam(which enables extended mode) fixes the menu issue. I can confirm that it works but performance is a lot worse as stated. Watch these videos carefully and then start trying out which settings work best for you.
