How big is the throttle bore?[/b]
You mean on the 09 DS? 46mm. DASA said there is plenty of wall thickness to bore it out but the company making the butterfly valve stopped so they have to find another one. I'd imagine they flow that whole intake TB and all and with their port air flow s/b pretty big n smooth.
