PROPERLY mounting your Boost Bypass Valve

I'm confused a little. Could y'all explain the purpose of the boost bypass?

I was messing around with mine a little tonight trying to set the mount in the right place. So I need to mount the bracket like Razor did and then unscrew the set screw a little?
 
There are 2 ports on the actuator.
The port furtherest from the bypass shaft (towards the front of a CTSV) is the vacuum; the port closest to the shaft (rearward in a CTSV) is the pressure.

BTW ...
12 noon PST = 7am in Melbourne (until daylight saving changes again).
Finally a simple image with explanation!
 
So at idle, the actuator pulls the blade open and the blade is shut when the car is off. I'm thinking out loud here.

I can't mount mine as far towards the engine as I should be able to because my adjustment screw is threaded so far in that it pushes on the rod, which opens the bypass blade. I had to mount the actuator as far away from the engine as I could. Somebody please correct me if I'm wrong.

I'm thinking about just ordering a new actuator.
