British Fighters -reduced engine power

[BobTuck]

I don't know how many of you fly with automatic engine management, but could someone tell me please how to overcome the (brit fighter) current problem of the power being reduced even though throttle is at max? At the moment Spitfires and Hurricanes are almost unplayable for me.

I've also noticed since beta patch install that not all the cockpit instruments are telling the truth (e.g. the artificial horizon, compass)

Regards,
