full movement of the lever and eliminated the plate stall inside
the venturi allowing full movement of the control plunger.
He said this was originally seen on an old Mercedes CIS and
they did some testing and then had one made for a 930 metering
plate and it worked so well they used them on their race motors
had them made locally and sold them through various Porsche
aftermarket suppliers.

If they worked so well, what happened to them?? That's what I'd like to get: a simple bolt-on.
