How to Turn Up an Audi TT Boost

1. Join the vacuum hose coming off the wastegate actuator to one end of the boost controller.
2. Connect the other end to the turbo outlet source line found on the compressor side.
3. Secure the controller with a zip-tie away from heat sources.
4. Turn the knob a small amount clockwise to increase manifold pressure, (boost) and perform a third gear full-throttle pass to measure psi (pounds per square inch) increase.
5. Repeat step 4 until desired boost level is reached. For safety use a deserted road or track to fine tune the controller.
