My passenger side was showing richer on the O2 gage so I pulled the plugs and they confirmed that side was definately richer. I know what my safe limit is on my WOT reading, now I am trying to determine how close I can get each side to each other with a dual plane intake on my sb. Is .4 good to you racers or do you like to see both sides a little closer to each other than that?

Thanks for the replies.
