Unless Neil installed a wideband since I last talked to him, that AFR was from the tailpipe on a dyno. They read a little leaner. The last time I got re-tuned, I datalogged through my wideband and also had the tailpipie sniffer. The tailpipe reading was about 0.5 leaner than my wideband reading.
So, I think he is OK
