TROUBLE SHOOTING

The following points should be checked if you find that your engine is developing excessive boost, the boost pressure is fluctuating or
the desired boost level cannot be achieved. Please note, the following checks will cure 99% of problems experienced when fitting a
Turbosmart boost controller.
• Check that the boost controller is installed so that the arrow points toward the wastegate actuator
• Check the joining hoses for splits, cracks or loose connection and are the correct size for the application
• Check to see if the boost controller is blocked or contaminated with dirt or debris
• Ensure that there is nothing but the boost controller in the hose between the pressure source and the wastegate actuator, ie tee
pieces for boost gauge or to factory boost solenoid.
• Pressure test the wastegate actuator for leakage, the diaphragm or housing may be cracked or split
• Check that the wastegate is operating correctly
