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 spring is designed to open under vacuum conditions to allow for the air to bypass into the exhaust manifold
