That's correct, the wastegate top port is open to atm, the side port goes to boost. I have a port on the pipe between the intercooler and TB that goes to the wastegate control valve which is then connected to the wastegate side port.

The red hose coming off the TB goes to the BOV which needs vacuum to open when the throttle is closed.

My MAP sensor is also after the TB so it can read vacuum and boost.
