One other thing, make sure you don't have an exhaust leak as it will give false readings too. Is the AFR you are seeing on the gauge or in EA? If it's in EA make sure you have the offset set correctly for the type WB you are using.

If all that checks you can either adjust the fuel table or the MAF curve to get it to matche commanded AFR. Oh and be sure you force open loop while doing all of this and clear KAMREF.
