Are you sure it isn't the BOV?

It's because the BOV does have a port that I believe is used to connect it with the intake manifold.

That what we said earlier. Because our cars have a returnless fuel system we don't have a vacuum source for the fuel. So what you do is tap the back of the intake manifold with 1/8'' tap NPT and install a 1/8'' threaded barbed fitting NPT into. That becomes your source for the boost controller. This is what HKS doesn't show for us.

The vacuum port for the BOV go to another barbed port that needs to be tapped behind the throttle bodies on the intake manifold.
