Intake pipe, any tests?

What I've read before is that since the stock intake tube has those "ribbs" it disturbs the air flow. So a smoother intake pipe should help some. Also read about a guy that wasn't seeing as much air flow as he should have with his turbo and it ended up being his stock intake tube that was restricting him. He also couldn't hold boost up top and the intake was the cause. Maybe it will help you hold more boost!
