How to Adjust Greddy BOV?

I just got my 93 rx-7 last week and I noticed that I can adjust the Greddy BOV from soft to hard. Does anyone know how to adjust it?

Thanks,
Jordan

Loosen the set screw and adjust with a hex driver. In for hard, out for softer. Soft vrs. hard relates to how easily the BOV will release. You are just adding or removing pressure on a spring that pushes on a disphram. You want it hard enough to keep from leaking boost before you let up. Any harder and yo may get some surge before it opens.
