This is kind of an addendum to Voodoo's ITB idea. With that out of the question, is there potential to improve airflow with either an aftermarket IM or a good port & polish? It would be good if the aftermarket tuners were developing something but I haven't heard of any doing so. How about a port and polish? Do you think there are any gains to be had there?
