No expert but pretty sure you want to see the numbers drop to around 11 on full boot.

 

14.6 is spot on for normal driving. 13.5 seems slightly low too?

What AFR gauge have you got? my AEM has a digital gauge around the number display which is coloured to correspond to the AFR reading. When on boot it's green at the low numbers, if it was orange or even read i would be very worried :)
