    Find someone with an air compressor with a regulator. Hook the boost only port on the wastegate to the hose on the air compressor (using a nozzle or whatever). Set the regulator on the compressor to about 50psi and try it. Keep in mind that there will be no pressure on the wastegate from the exhaust so whatever pressure you use on the compressor divide that by two and that will be right about where it'll open. You can do this on or off the car. On the car might give you a more accurate idea.

    it also will depend on how you have vac. setup and where. also where your waste gate sits on the mani. several variables involved. just because it tests at 89psi doesnt mean thats what you get when you hook it up.

    Notice how I said its approximate. There's no possible way to manipulate it exactly. But driving the car and figuring out where it opens is not a good idea. Especially because from the sound of it the car isn't tuned. Bad idea.
