What signs indicate that my valve is adjusted too hard?
If the valve is too stiff, then your vehicle will generally exhibit some level, large or small, of compressor surge (also known as turbo flutter). This sound may accompany a delayed (and short in duration) release of the air charge from the valve, or it may be present with absolutely no opening of the valve at all. In general, compressor surge can cause damage to the turbocharger and should be reduced or eliminated whenever possible. If these conditions are present, then the valve should be adjusted softer.

What signs indicate my valve is adjusted too soft?
If the valve is too soft, then your vehicle will generally suffer from a valve that is open when it shouldn’t be (such as at idle) or from an extended air charge release (possibly in excess 3 seconds). If either of these conditions occur then the ...
What’s the difference between a “Dual Port”, a “Supersonic”, and a “Plumb Back” valve?
Our “Dual Port” valves split the released compressed air, recirculating a portion of the air into the intake tract and removing the remaining air into the atmosphere. A “Supersonic” valve vents 100% of the compressed air charge into the atmosphere. A ...
Why/when/how would I adjust the valve?
Most valves come pre-adjusted to the correct setting for your vehicle. The two possible extremes that may require adjustment are a valve that is too stiff for your application or a valve that is too soft. If the valve is too stiff, your vehicle will ...
How much boost can a valve hold?
Our valves are not rated by the amount of boost pressure that they can hold. A good rule of thumb is that if the hose supplying air into the top chamber of the valve is large enough to supply an adequate volume of air, then the valve itself should ...
My valve is not functioning the way that it should be. What should I do?
The first step would be to perform some basic inspections on the valve and try to establish what potential causes might exist (such as a leak or an incorrect spring). If the valve is a piston-type valve and has not been maintained (cleaned and lubed) ...
