(1)

Inspect the installation. Reconnect the negative terminal of the battery and start the engine.

Check and make sure that there no air leeks, clearance problems or irregular sound.

(3)

Lightly rev up the engine couple times to check if the blow off valve is operating.

If irregular idle or engine stall occurs, loosen the M6 lock nut and turn the adjustment screw to
HARD

HARD

HARD until the problem is eliminated.
After the adjustment, tighten the lock nut to secure the setting.

※

The adjustment is preset to the softest position form factory. Do not turn it further out that

this position.

※

Make sure to loosen the lock nut before making adjustment. Turning the adjusting screw

without loosening the lock nut will strip out the top housing.

※

When the adjustment screw is turned in, the stock of the valve decreases. Screwing it in too

far will affect the proper operation of the valve.

When venting the outlet to the atmosphere, depending on the application, the airflow meter
voltage can drop enough to stall the vehicle when the blow off valve is discharged.
If adjustment of the top screw cannot prevent the engine stall, install e-Manage system and use
the Anti Engine Stall feature or reroute the discharge outlet back into the intake system after
the airflow meter.

If the engine stalls while operating the vehicle, the steering and the
Brakes will not operate properly and can be very dangerous.
