You most defenetly have to remove the tube that goes from the TB to the filler neck on the valve cover. With a blower, the discharge tube is always positive, even at idle. Behind the TB, its negative pressure. It is at a negative pressure while at idle and most of "normal" driving. It only goes positive when you have the TB wide open and you start supplying more air than your engine can use .... backpressure. What you were doing is always blowing in air to your crankcase. Not a good thing. You are seeing the results.
