Also shouldn't the gate work with just spring pressure if there is no pressure at the bottom of the port?

No. If you aren’t applying pressure to the bottom port of the gate it would never open. The WG opens based on turbo pressure, or manifold pressure, depending on where you are taking the source. The exhaust gasses in the piping, pushing on the valve seat of the WG, are basically at atmosphere since it’s open all the way out of the muffler. That’s simple hydraulics.
