A/F Ratio at Idle

A/F Ratio at Idle
I just installed a wideband in the car and the idle seems to be running lean in my opinion.
Mods: Pettit ECU, intake, full exhaust w/highflow cat, upgraded IC
A/F ratio at idle: 16.5-18
During normal driving it hovers around 14.7-15.5 and at WOT its somewhere around 10-10.5 @ 12psi
I thought it should be sitting around 14.7 at idle as well. Is this not correct? If so what would be wrong with this setup?

Oh right I totally forgot about the air pump.
I know 10:1 at WOT is very rich but seems to be how the Pettit is tuned. If I run anywhere from 10psi to 13psi it starts around 11:1 maybe around 5,000 and goes down to 10:1 as I get to the redline. I really don't mind, just give me this safety margin I guess.
Thanks guys!
