Spitfire II quirks, questions and anomalies

[Crashlight]

Just running on simple engine settings, the Spitfire doesn't have Boost although I have seen it activate on autopilot. Same settings, the Hurricane boost worked fine, making it a better fighter than the Spitfire is. ???

Anyway, Boost never activates on simple engine management settings even with hotkey activation of "T" and "W" whereas the Hurricane does it automatically with no hotkey activation. I guess a fix is coming or is there a workaround?
