Make sure you set the hoses up exactly as stock. The boost pill on that car is on the turbo manifold side of the tee, the other side goes to the waste gate actuator and the top of the tee goes to the boost control solenoid in the car.
After you install it all and using the cobb ap you will be able to log or check boost levels to show you have done things right.
thanks much appreciated.
