RPM setting for low level cruise is around 2300-2400 RPM
Manifold pressure would be around 22-23 inches
For Final, you will probably ultimately have the props fully forward (=2600+ RPM) and the manifold pressure between 15 and 17.
I haven't seen the simulation, it would be interesting to compare it with the real thing!
