I highly disagree with your assesment of the F-5. It may not be very complex but thats just how the airplane is and is a great moduel.

The reason the plane is shaking above 1.45 ata is because you are causing engine knock above 1.45 ata. The MW50 is used to prevent knock and allow higher manifold pressure and therefore more power. The limit of 1.45 is mostly due to the fuel octane rating, B4 has roughly 90 octane while german C3 has about 100 octane. Other versions of the DB605 uses C3 without MW50 and can run the same manifold pressure as the other version with it. This is why the D9 also has MW50 normaly used where as the P-47 has a smaller amount and can produce much more manifold pressure because it uses a higher octane fuel, i belive 130 octane is the dcs version.
