Can someone tell me why some would have MAP guage and some wouldn't?

Most of your basic single trainers will just have a fixed-pitch propeller...where throttle controls RPM.

Constant-speed propellers are found on higher performance engines where the throttle controls manifold pressure and prop controls the pitch of the blades which translates into engine RPM.
