Please look into working on the turboprop propeller range and turbine simulation. The different reactions of propeller pitch angles vs throttle settings at different density altitude.
Also the possibility of having different turboprop types:
Free turbines like the PT6 series or M601/H75
Geared turboshafts like the garrett TP331, GE T700, and Allison T56.
They all have different procedures and ways they all react to different conditions.
