Taken directly from the manual:
Stand-alone Installation: If Evolution Wastegate is to be installed as a conventional wastegate, the
boost sensing line (bottom port) may be connected to any convenient manifold pressure source, such as
compressor discharge or intake manifold plenum (plenum runner locations not recommended, as they
may cause pulsing which may affect control stability). The top port may be plugged with a filtered vent or
connected to the air intake system after the filter.
