The top left nipple on the TB is the only vacuum source to use. This port only recieves a signal (vacuum/boost) once the throttle is opened past idle. This keeps the recirc valve from staying open at idle/decel.

What would happen if I did not recurclate? |
The PCM in a mass air controlled vehicle delivers fuel based on (among other variables) the mass quanity (gm/s) of air that passes through the MAFS. The computer has no means to determine that air has been purged from the system (blow off valve) and sends fuel for the air which it's logic determines is still present.

I dont agree with the concept of a universal valve without spring pressure adjustment. The spring must be heavy enough light enough to allow proper valve modulation (response and lift) under varying conditions yet heavy enough seal the valve under heavy vacuum/boost.
A universal spring rate may be to heavy for some set-ups (experiencing compressor surge?) and to light for others ( intake of unfiltered air/ boost leak). This should not be a "one size fits all" components.
