Two Stage Boost Control Solenoid

This is plumbed into the intake pipe, then " T Pieced" off into the bottom port on the solenoid, while the other vacuum hose is connected to the Actuator.
The top port of the Solenoid is plumbed into the recirc pipe.

The purpose of the solenoid is to adjust ECU settings when running on the max boost level permitted by the actuator.

As standard these settings are 0.4 Bar for the first stage, and 0.6 for the second stage of boost.

More information will be made available soon on the workings.
