If that hose comes off the middle (side) of the factory WG body, it's supposed to be the boost signal, and should be connected to the pressurized portion of the intake somewhere. Without it connected, there won't be any boost regulation (WG won't open because it'll never "see" the boost).

If it's an aftermarket WG, check what the manufacturer says the ports do...
Well the top of the WG is open it seems so should I put on a bango fitting there and put a hose to the air box or is it ok the way it is??
