AFR calibration and setup

Hi,

I would like to confirm what I think from what I have read on forum for AFR setup...

I install a WBO2 and I see that I running 14.2 at idle(stock map), I tought I would be more at 14.7. Is it normal or when I have done the calibration, I have mist something?

I think calibration was good because it read 21.9 when was not in the exhaust at ''free air'' but...
I have a Intake, I know this can altered the AFR.

And from what I read, I can run like 16.2 for fuel economy and the zone of like 500-3500rpm and 0%-70%load?

And I target 12.5 for best torque (something like until 4000rpm at high load) and I taper it down to 11.5 at 7000rpm?

(I have full TBE, Injen intake and lower/upper piping, o2housing, grimspeed3port and 4bar map for direct boost control and boosting to 25 psi tapering to 21 at redline, modified MIVEC and timing map, on tephra V7)

Thanks!
