A further thought. The air flow metering units are, as far as i know,
of the hot wire type, how will the system react to venting boost to
atmosphere? I am aware of problems with the swinging gate type AFM's
not liking sudden venting of boost and sending the mixture mad rich for
a few moments, what about the hot wire type? Or is sending the mixture
rich at gear changes / lift offs, a "good thing" in so far as it helps
cool things down? Funny how a simple job has so many
ramifications...:-)

Thanks.
