you can see if its in there, or even search under the Allison engine it used. Just see at what RPM it gets the best torque.

Its also my observation that most planes with CSP (constant speed propellers) fly at their optimum torque settings with 100% pitch.
I know there are a handful of planes that require 90% or 95%, so it is worth checking.
