This is what a dev said in respondse to a P-51 topic:
So last updates: we have found some issues, that were indeed in the game. Long story how it happend, but it is fixed.
Also, good guess from you, guys, help us to increase performance of P51 - it has full fuel tanks, and this decreased it performance.
I 'hope' that the 'we have found some issues, that were indeed in the game', affected more planes. Because the FW190 is indeed not performing as well as it should be. It aint very bad, but it is not like it was in the PC version, and according to the devs, it should be.
We will just wait and see
. I have high hopes that something will be fixed, that was keeping many boom and zoom planes, from reaching full potential
