• 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.
