Thrust Scaler Not Working

I have done basic flight model modifications but I’m not a developer. I’m trying to work on the 747 since the default airplane is way overpowered. The thrust scaler in the engine file has no effect. I reduced it from 1 to .00001 and there was no difference. I resynced after making the change and even restarted the sim entirely but there was still no change. Is this not the right place to modify engine power? I could not find anywhere else. Thanks in advance for your help.

This is happening with me on turboprops. Cant figure out why. Watching this one.
I am using SU8, not the SU9 Beta.
