I think the reason the wedge doesn't help as much is because the wedge actually makes the inside circumference of the tube smaller and less air can get through.

Keep at it! I would like to have one with matching tube diameter to the plenums. The 997 has an OD of 97mm. Much larger then the Plenums opening.
