Procharger question?

Just installed an F1 and it's intercooled. The problem i'm having is that on wot the the blow off valve isn't closing, I can still hear air coming out. I have the valve with the vents on it. On the base plate i have the blow off vale T'd off with the timming retard. And on the carb bonnet i have the boost gauge and the fuel pressure regulater.

That valve should close at 0 vacuum.The vacuum line to the blow valve should be taken under the carb.I connected my blow valve and boost gauge from under the carb and boost retard and boost regulator from the carb hat.You will not make vacuum without a load on the motor.
