| The boost pressure that the valve's pistons are exposed to is post intercooler also known as before the throttle valve but AFTER the intercooler. The pressure/vacuum that the valve's diaphragms are exposed to is post throttle valve (intake manifold). The distance between these two points is negligible the "pressure drop" (pressure differential) between these two points at WOT is not high enough to overcome even the whimpy stock recirc's springs. So, if you got the doughnuts, I got the dollars.
