ooh, ooh, I have an idea and no one has mentioned it yet. add a tube in that connects both ends of the IM (opposite side from the TB) not exactly sure how it works, but it does. Every high performance or "expensive" engine that uses a IM similar to the duratech I have ever seen incorporates this.
Just whip out you TIG and wled on say a 3/4" tube right off the end of the upper intake manifold to connect both ends together.
