Keep in mind prop valves are like carburetors.

There are multiple "tunings" and configurations released based on GVW, brake system, wheelbase, etc.

You really can't just grab one randomly and throw it on without knowing what it came from, or ideally the meter/split/slope characteristics of that specific valve.
