How to Install a Manual Boost Controller on a Passat

1. Attach one side of the manual boost controller to the vacuum hose coming off the wastegate actuator (located on the back of the turbocharger unit).
2. Connect the other side to the boost source outlet nipple.
3. Secure the controller with a heavy duty twist tie (included in the kit) away from the exhaust manifold.
4. Do a third gear pull by flooring the throttle when rpm is at approximately 2000 until redline on a closed stretch of road or track. This will set a baseline and determine the vehicle's exact factory boost setting.
5. Adjust the turbo boost setting on the MBC by slowly turning the knob in the desired direction. (typically clockwise will increase boost pressure and counter-clockwise will retard boost)
6. Complete several full-throttle passes to attain a specific boost setting.
