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