Message Connect S2 to your manifold (after the throttle plate) Connect the S1 to your boost controller and then to a pressure source between the turbo but before the throttle plate. Here is why.

When on boost - both sides of the actuator get pressureso the spring can do its job fully. You get off the gas - the throttle plate shuts - the S2 port gets vaccum while the S1 port still has boost (since its b4 the throttle plate). THis causes the w/g to Snap open FAST.

Benifit of the dual port setup is that the boost response is sharper and the boost controller can control the boost with fewer spikes so you can get away with bumping up the gain quite a bit on your BC.
