I realize that the P-51 CoG was moved but,

Current P51 FM is very close to what pilot accounts like Bud Anderson memoirs read. It is nowhere like a P51 with full aft fuel tank, or you'd have to PUSH the stick while in a turn so the plane doesn't tilt itself beyond control. If you find it difficult to handle, you can either train (it doesn't require much time) or lower your joystick response (doesn't take more time). Just leave the FM alone, pretty please.

BTW, if you can still find it, UF josse made a mod with moving CG, and flying it with full tank was really a challenge until it started to empty. Compatibility was 4.09 IIRC.
