I do too, but the issue is that the P-51 was kind of made for just flying about, while the Fw190 was made for the more competitive DCS-1945 scene. When the P-51 module was made, it didn't mater how many inches of hg it was pulling, as long as it was authentic.
It's shows in how highly tuned the Fw190 is as opposed to the P-51, even with it's extremely rare gun sight. Out of curiosity I wonder how many actual D9 performed like the one we have in game.
P-51 was a great modules for DCS when all you could do was fly the P-51 and fight against a unfinished Fw190, but it needs to be updated to 1945 standards, for a 1945 competitive setting.
