Yes, NOx increases with temp. But doesn't it increase with more available oxygen too? All I know is that a lot of guys report lower temps at 16:1 AFR and leaner. Please correct me if I'm wrong. Of course there's more to it then just AFRs. There's load and timing too. The guys reporting lower EGR's while running 16.5:1 AFRs are for the most part doing that at part throttle, but enriching it to 13-12.5:1 for full throttle.
