AFC changes: Lean 15% from 3000 rpm to 7000 rpm

NOTES: Due to the street tires, I could only launch at about 2500 rpms. Otherwise I'd get wheel hop and massive tire spin
And then take a look at the 1-2 shift. My tranny is slipping. Thus only 111 mph traps. And the 15% leaner setting on the AFC
produced low to mid 11 A/F ratios.
