How re you gathering your AFR reading? is there s sniffer in the exhausts or a reader directly in a bung on each cat?
From my experience any digital read outs your seeing from the cars computer should be disregarded. I had nothing but issues with my tune till we used an actual sniffer or took readings directly from the cats.
