Attention: TDR Forum Junkies 
Tried to put this in the original post-but apparently I clicked on "new topic" instead of "reply to topic". Couldn't manage to delete it either so I guess I'll just modify it a bit.
The Roda Deaco air shutoff isn't a butterfly valve either. It's a swinging disc that sits completely out of the airflow path when not actuated-so there's no restriction in airflow. We're at better than 3000' altitude here-with an EZ on my truck I see anywhere from 26-28 lbs. boost measured at the intake manifold under WOT-so if it restricts flow it can't be very much anyway
