The acceleration of the 190 is probably too poor ingame. Reports from wwiiaircraftperformance.org confirm this:
Navy test, Fw-190A5 vs. F6F-3 vs. F4U-1
"Relative accelerations, for all speed over 160 knots, showed both the F4U-1 and Fw-190 to be slightly superior to the F6F-3 and showed the F4U-1 to be slightly superior to the Fw-190 up to 15.000 feet, above which altitude, the Fw-190 had a slight advantage. At speeds less than 160 knots the F6F-3 and Fw-190 were equal."

Another report, again Fw-190A5
..."The run is short as the aircraft accelarates rapidly"...
..."Airspeed acceleration after take-off is noticeably good"...

According to these, the 190 had good acceleration. Ingame, its mediocre at best.
