There are many options. Ball and spring manual controllers are the prefered after the electric solenoid ones like you have. Depends what people have lying around or easily available to use.

Good useful thread to a new s12 owner :-)

Also fit an aftermarket boost guage before trying to set up your boost pressure increase. Try getting one in psi showing 1psi increments as this will be the most clear to read and setup in my opinion.
