If you have a map (Bluefin or whatever) you dont need a bleed valve or boost controller.

Leave the original solenoid connected electrically just remove the hoses.

Fit a forge actuator with the correct spring.

Connect the hose from the actuator to the turbine housing. Use a boost gauge to set what boost you want. (22psi should be fine)
