The gauges on the FW-190A's cannot be simulated under Aces High so no one can really say if they are at the correct boost.
Nor can the Kommandogerät's operation be simulated either.
Kev, we are not talking about what the gauge says in the graphic's showtime of the cockpit anyway.
I am refering to performance in the air.
For example, it appears the AH FW-190A8 is based off of these charts:

As the chart says this if for a
NORMAL finish FW-190A8 and represents a chart of
uncorrected speeds.
When you run this data through Focke Wulfs position error corrections, you get the published data Focke Wulf guarenteed the FW-190A8 could achieve [/b] on average[/b] in True Air Speed, not the Calibrated Air Speed of the chart.
The on average part is why you can find FW-190A8's doing 585kph TAS on the deck. It is almost exactly 1.5 % above the published figures.
Now how come there is no outrage from Spitfire fans who want to see a correctly modeled Spitfire when the data exceeds Supermarines guarenteed percetages?
Personally I don't think it is far enough outside the swath of achievable performance of the Spitfire Mk XVI to warrent correction in and of itself. However if the Spitfire Mk XVI is not representative of the type's historical abilities and unbalances gameplay, then by all means it needs to be corrected.
It certainly might warrent attention if it's high altitude performance is out of the realm of possibility.
All the best,
