A design I stole from the Supra list uses a pressure regulator. I'd think
that is more accurate. For cheap regulators I frequent a salvage yard
that gets lots of automated controls stuff. They never charge me for the
plastic regulators since they just want that out of the yard.
I've given away several new precision regulators and
can get any size pneumatic actuator imaginable.

If that helps.

Call me cheap.

There is an interesting variation on the regulator or bleed valve idea. An
on/off solenoid on the exit of the regulator (when used as a vent, rather
than in line) allows a toggle switch to change boost from the basic setting
of the wastegate to the higher value controlled by the regulator. When
closed, and no venting, the system is under w/g control. Open, the regulator
controls. Advantages are: always the same number unless the reg is
readjusted, instant change either up or down, don't have to look at gauge
while under boost to adjust.

If you can't find the pieces, we have them. Not cheap, as usual.
