the wastegate should still be hooked up to the snail. gauges, fuel regulator and bov should be manifold. if the wastegate isnt opening you would know the boost would go crazy high (overboost). this may be a dumb question but are you sure you hooked your wastegate actuator up with the door in the closed position? i.e. can you push the rod out to swing the lever attached to the door? it will be a little hard may need pliers to get a good enough grip to do it.
