Boost referenced my holley to use the spark port on the front metering block to get vacuum for the power valve so it operates correctly. This is the back of my supercharger in the picture. I assume I need to connect it to a "standard vacuum port" and not the smaller "manifold vacuum/boost port" correct? Or do I need to connect the manifold vacuum/boost port to the holley? This has me a bit confused. I have the manifold vacuum/boost port connected to the 2 bar map sensor for boost retard. I can T it off and connect it to the carb also if that is where it needs to be.
