When NJ had regular gas I could close the GAV, I ran the car on the emissions dyno, 4%co, later with ethonal gas I ran it because the gav needed to be opened more, closed the co was 0.05 co, too lean to drive, the exhaust manifold would glow red, at 1/2 turn 3%up to 50 mph, to have 3% above 50 needed 3/4 turn, my jets have not been flow tested so I don't know how they compare to the"standards "
