I hadn't thought of that Greg. I'm using the Mast relay built into their harness. I will double check it.

This could be part of the story but isn't the whole story as I can duplicate this behavior on the freeway with the fan off. I turned the fan off with my laptop and saw stable temps ~210* in 6th gear 70mph but when I ran 4th gear at 70mph the temps dropped to below 200*. So I think there is something else going on too.

Regarding lean vs rich. The car is pretty stinky right now and if I don't clean it builds up a layer of soot on the tail panel so I think it's to rich. Oh and it gets horrible MPG. Around 10mpg around town. A best of 15 on 100% freeway drive.
