• Check that the eBoost solenoid is installed correctly.
• Ensure the factory boost control solenoid is not connected in the hose between the pressure source and the wastegate actuator
• Ensure the length of the wastegate actuator rod has not been modified, refer to the manufactures specifications.
• Check to see if the e-Boost solenoid is not blocked or contaminated with dirt, oil build-up or debris
• Check the joining hoses for splits, cracks or loose connections and ensure they are not blocked, kinked or restricted, particularly if the existing hose was reused
• Pressure test the wastegate actuator for leakage, the diaphragm or housing may be cracked or split
• Ensure the smooth and free operation of the wastegate arm in the turbo exhaust housing.
• Check that the hose between the eBoost and the inlet manifold is not obstructed, broken or kinked.
• Check that the OBS is set higher than the boost pressure you are aiming for.
• Check the Blow-off Valve for leakage, some are used as over-boost valves
• Gate pressure may be set too close to your actual boost pressure – ensure correct sensitivity setting.

• eBoost will not work with vacuum-operated wastegates.
