Yeah my Innovate wideband was reading a little richer than the sniffer, but not as far off as yours. The guy running the dyno said that the sniffer is very accurate, just a little bit delayed because of the length of the lines, etc., but at Mainstream they told me the sniffer on their DynoJet could read .5-1.0 off at times. I think I noticed that the sniffer only went in one of your pipes. I don't know where your exhaust splits, but perhaps that could've had an effect on it too.
