I'm wondering why there is a vane in the cyl heads at all. I could see for n/a, but FI? what good is a vane? Is it just for fuel economy or emissions or? Does anyone know?
Also what is the butterfly seen in the inlet housing. That seems to be a big restriction to flow right there. Is it the boost bypass? If it is I know what's happening to mine when I get in there...
