Oh yes it does work indeed, from sea level all the way up to some 12000ft. Gauge reading is only +8lbs (wrong on both 100 octane aircraft, but the other way around)
All you have to do is:
1. Pull the tit
2. Wiggle your throttle back and forth (otherwise nothing happens)
3. Voila - we have BCC-O activated, boost gauge now reads +8lbs (I assume that's just a bug as the performance feels like +12, also wrong on Spitfire)
glitch: you have to set the mixture to lean in order to use it at 3000rpm as intended, on rich there is 2600rpm max (engine will shake the Dickens out of you if you don't). Speed on S/L is greater and the manifold pressure decreases nicely as you aproach full throttle height.

Probably explains the attached. Don't bother speculating.
Back to the cockpit.......
