External wastegate

My favorite method is to use a pneumatic pressure regulator. Feed the turbo boost pressure directly into the lower port of the wastegate and tee that off into the regulator which is then set to feed a regulated pressure to the top port of the wastegate.
This way, with a 1.5 bar spring in the wastegate and the regulator feeding 0.8 bar to the upper port, you'll get 2.3 bar boost.
You can also just use a regular manual boost controller, but then you leave the top port disconnected and plumb the boost controller into the lower port.

None of it,I want to know is how to use a manual boost controller in an external wastegate..
Like for example,the external wastegate has a spring 1.5bar and I want to do 2.3bar
