Yeah. You pretty much nailed it
It controls a vac solenoid to set where you want the vanes in response to throttle position, RPM and current boost against a look up chart for requested boost.

Right then, Where do I get one of those from or is it some kind of kit I need to build? What kind of cost is involved too? Thanks for the reply.......Luke
