You would think a refuel would reset wep back to 100%
Pretty sure it works in the 109s after refueling

I think that depends on the type of WEP the plane uses.
The p51 just had about 10% blocked off at the top of the throttle travel and you had to pull a pin to use that last 10% and you could run it until you blow the engine .... but even below full military power you can blow the engine.
The P&W double wasp air cooled engines used water injection. Once the water is gone wep is gone.
Many of the European planes used Nitro Methane injection with the same issue that you have with water injection, once you are out of Nitro your done until you land and rearm/refuel.
However Aces High does not accurately model Wep or Engine management any way.
