I'll check the connection again, if I recall the boost signal comes from a tap on the charge pipe just before the IC. So that could cause it to act like a BOV? That won't harm anything will it? Do I need to re-do the plumbing and find a spot on the manifold?
This is the correct method of hooking the plumbing up. The wastegate will not operate like a BOV in any configuration (unless the spring was broken) as the spring tension holds the valve shut until boost pressure overcomes that tension and opens the valve. If you are using a MBC, the line from the MBC should go to the bottom of the can of the WG and the top of the can should be open to atmospheric pressure.
