Thanks for the many view points on this subject. I did have the top end rebuilt 2000 miles ago. Noticed that my plugs exhaust ports were crusted with deposits when I installed the B&B headers. Pulled the plugs and found that all were crusted equally as well. From my spark plug observation I don't see a hot cylinder in the mix, although plug reading is hardly a scientific approach to quantifying the injector output!

From the conversation I'd say that:

1. possibly my CIS is not working as well as it should
2. I could go leaner on my mixture
3. Keep the WOT no more than 12 to be safe
4. acquire the additional measuring devices to further fine tune my results

What about the no load AFR? I suspect that if I lean out the WOT to 12 that my "no load" AFR will be higher than 14.7. Should I be concerned?
