The Conquest/Starion had a solenoid that was hooked up just like a standard boost controller. For a 5 speed car, boost was limited to just 7.5psi until the car hit 4krpms, then the solenoid would switch to the 10.5psi port so long as knock wasn't detected.
On an Auto, the 10.5psi port was used all the way to redline, unless there was knock then it would kick it down to the 7.5psi.
You can use the 7.5psi port, along with a bleeder style, or EBC, boost controller to achieve whatever boost levels you want. But you also have the ability to simply limit your boost to 7.5psi by supplying the port with unbled intake pressure.
I just think it would be a better wastegate actuator to use, as I do believe the 1G DSM was at 10.5-11psi, so to achieve your 9psi you want, use the 7.5psi actuator and a standard bleed style controller(like a Lindsey, or the Home Depot variety).
