set gain to 1/3 (of the knob marks)

the set the other knob (lo) or (hi) to dial in the amount of boost

about 1/4 or 1/3 gain usually works the best for SR

^ exactly what he said.

I run that one and i like it alot.
Good boost controller.

its all in percentage though... so like 33percent for the set gain. I am running an s15 turbos with the accessories. 555cc injectors, z32 maf, fuel pressure regulator.

The profecB spec II 's user manual makes no sense at all, all lost in translation.

you would think Greddy would have some who was engrish translate the instructions.
