FD T/B and upper intake polishing.
 

I have a ground zero lower intake manifold on the way and am looking at the UIM for improvements in airflow to support it. I have removed the double throttle plates and am thinking about polishing down the walls, removing the double throttle tubes and combining them into one and tapering the first divider off comming out of the main butterflys. Does anyone have any thories on doing any of this on a heavily ported motor running high boost?
