Does a constant speed prop deliver max speed at max manifold pressure and max RPM? I was reading a discussion in flight simulator forum and I found this statement:

Ignoring the issue of engine overheating, max MAP and max RPM is the
best thing for max speed

Do you agree with that?
Assuming a Constant Speed Propeller.
For maximum speed, you need maximum power from your engine. This means running it at its maximum rated RPM with the throttle wide open, and maximum manifold boost pressure for a supercharged engine. The prop governor will then adjust the prop pitch to put the biggest possible load on the engine at that RPM.
