Important notes on Boost Pressure
If boost spiking occurs and is undesirable for your application,
the gate system can be removed to give you a less aggressive

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
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
