Heres my AEM Uego air fuel ration guage. As you will see It goes rich to about 13.6 during acceleration, and goes off the scale lean with the foot off the gas.

started out crusing at about 50 mph, when I floored the pedal in 5th gear, and then let off when i hit about 60, and then got back to cruising at 50 or so.

mind you that i have the Apexi air fuel controller hooked up, in the hi throttle settings corrected only, the lo settings are left at zero. I believe the correction is about 17 across the board to redline.

enjoy
