AFR needs to be over 13.5 at idle to be in on the emissions test. Really you should have no trouble reaching 14.7 at idle.
Just make that part of the map nice and lean to get through the test. May affect just off idle performance, but you can always tweak it after.
AFR is a very unstable figure anyway due to the exhaust pulses. If you can average 14.7 and run nice an smooth I would be happy.
Do remember with forced induction you need to run much richer mixtures throughout the rev range. 12.8-13.5 isnt uncommon.
