Nice find ^^^ I like the valve feature, although it seems to operate differently than in the Akra (here it is a function of the boost level, as opposed to keeping it either fully open or closed all of the time [i.e. regardless of boost levels] like Akra's functionality allows you to).
Is it me or is that interior red???
