Cody from FITECH told me that their system works with both duel and single plane(of course they said that) but he told me that the single plane or a duel plane with an open riser/spacer work the best. If you are running a duel plane he said that the base of the TB has an X pattern notch in it. Since I had the duel plane I just added a 1" spacer that was open, Actually it is an adapter plate from the spread bore to the 4150 flange.
My TB is still on back order so I installed a Holley until the TB comes in.
