How to Install a Boost Controller (standard turbo, non-VNT)
1. Locate a source of turbo boost pressure for the input side of the MBC (manual boost controller). This can be a port on the turbo outlet or the intake manifold. Connect a hose to this boost source and use a hose clamp or cable tie to hold it in place.
If you are unable to source boost from one of these options, an alternative method is to drill and thread a hole in one of the intercooler pipes and install a pipe thread hose nipple. Hint: The closer you keep the boost source to the boost controller, the less spiking you will experience.
There is a rod that extends from the rear of the actuator and connects to the exhaust side of the turbo. This is the lever that controls the actual wastegate.
Dawes Devices MBCs are impervious to the heat from the turbo, but use cautions with other boost controllers, as they may be damaged from the heat.
