What pressure is your vacuum gauge reading when you run it at full power with the vac port blocked off?

And is the valve bleeding air at13?
The whole idea of those valves is that they don't bleed air until the pressure reaches its preset limit, unlike standard valves that bleed before the set point and lose performance.
Try allowing some air into the port so that the pressure is say 10. The valve shouldn't be bleeding air, if it is there is a problem.

Take it off and examine it, it may just need a clean.

Also check the fine filter that protects the blower.
