You're lean from about 62 mph through 90 mph - and very very lean (dangerous?) at 80 mph.

For comparison:
My last dyno run (July 9th, 2011 at Carlisle), my AFR was between 12.17 and 12.85 for the whole run. On another run, he didn't apply full power as soon, and I had high AFR numbers near the beginning (14.02), but they dropped as soon as he put the hammer down. But they didn't drop below 12.00, and hovered in the middle 12's. 12.2 is ideal, but you want a little wiggle room, so mid 12's is good. 11's are bad and 10's are even worse.
