SETTING BOOST PRESSURE
IMPORTANT NOTES ON BOOST PRESSURE ADJUSTMENT
•
Adjustment to your boost controller is made by rotating the Boost Dial
•
Rotate in a clockwise direction to increase boost and the reverse direction to decrease boost
•
Before making any adjustment, the Boost Dial will need to be fully closed (anti-clockwise)
Step 1: Apply full load to the engine in a high gear (at least 3
rd
or 4
th
gear) at full throttle and note the boost pressure
Step 2: To increase the low boost setting, rotate the Boost Dial clockwise (maximum of 1 complete revolution at a time)
Step 3: Apply full load to the engine and note the boost pressure
Step 4: Compare the actual boost pressure with the desired boost pressure. If the actual pressure is below the desired pressure,
return to step 2. If the actual is above the desired boost then decrease by rotating the Boost Dial anti-clockwise and return
to step 3.

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
