AFR's at idle

Mine idles between 10.6-11 and was about to make a post about it. It idles a little rough but drives fine, but to Reted, it doesn't seem to "like" where its idling. I've been using the idle adjust screw on the top of the TB, but its almost all the way in (can't raise idle an higher) and it still adles around 700rpm. I don't have a BAC, could adding on help any? What could manipulate mixture (so to speak) on an s5?

90 vert
stock t2
550s, 720 sec with Rtek 1.7
no emissions
throttle body mod
FMIC
*TPS is adjusted, though I haven't checked voltage range at ECU
