Install a toggle switch inline with the ignition source wire between the boost controller and the voltage source. Mount toggle
switch where desired.Install a 1A (amp) fuse inline between the boost controller and the voltage source. The fuse to be as close to the voltage
source as possible.Toggling the switch on and off should activate and deactivate the second stage in your boost controller respectively.

Step 2: To increase the low boost setting, rotate the Low Boost Dial clockwise (maximum of 1 complete revolution at a time)
Step 3: Apply full load to the engine and note the boost pressureStep 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
Step 5: Once the low boost setting is complete, follow step 2 to step 4 on the High boost dial . BOOST SPIKINGIf boost spiking occurs and is undesirable for your application, the gate system can be removed to give you a less aggressive boost
curve. This modification is only required in a minimal number of applications. Boost spike curve Ideal boost curve IMPORTANT NOTES ON GATE SYSTEM REMOVAL The gate system can be removed by the following steps. Perform this modification on a clean bench so that the ball and spring are not lost Allow the engine to cool down before removing the boost controller from your vehicleIdentify the input nipple with the restrictor at the end on the DSBC tee piece. Loosen the input nipple and remove the ball and
Check that the internal air passages are clear and free from debris Re-install the boost controller by following the instructions for your setup You will need to re-adjust your boost settings after the removal of the gate. Input Nipple with small hole DSBC Tee piece Wastegate Arrow TROUBLE SHOOTINGThe 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 actuatorCheck 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 debrisEnsure 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 DO NOT USE ANY TURBOSMART PRODUCT UNTIL YOU HAVE CAREFULLY READ AND UNDERSTOOD THE FOLLOWING AGREEMENT.Please call if you have any questions or do not understand this agreement.
