This Improved 'working ratio' is achieved through an increase to the effective surface area of the diaphragm & revisions to the actual springs fitted resulting in greater leverage of the forces the actuator is working against (boost and backpressure) while still being super-responsive

The Dual Port is a 50-50 recirculation/vent-to-atmosphere valve for that classic vent-to-atmosphere sound at high boost

which in turn requires top level driving skill and ability to adapt to a new setup
