What dyno's are you looking at? From the dyno's above that Drew posted, his AFR's are richer than yours up top, not the other way around. And also be sure to remember and take into account that Drew is running cats, so the tail sniffer will read leaner, whereas you are catless, in which your AFR's are more accurate from the tail sniffer.
