Default '-31 ACT' Spring Pressure.

How many Psi is the spring in this type of actuator set for.

I'm trying to see how accurate my electronic boost gauge is.

I'm getting a reading of between 13Psi and 14Psi.

Sorry to hijack, what is the hold psi on a -34 actuator, and is a -31 actuator the standard one on a big turbo escort cosworth?
