Question AFR - ideal 90 degrees IC outlet vs. 140 at the track - what's the diff. in density?

I've adjusted the AFRs so they are pretty slose to perfect - 12.0 to 12.3 all the way up...

Situation is under ideal dynamometer conditions - IC outlet temps a nice comfy 90 degrees.........all was good.

So what is the difference in air density - and thus the theoretical "textbook" difference in AFRs from this ideal, to 140 degrees on track under full on track use?
