Enrich power change to AFR vs RPM

Curious about this setting in Tunerpro 5. I figured out the formula for this and it looks like if i use -7.25 throughout the rpm range it should come out close to 12.7 AFR. I am trying to understand how to set this table up tho. My car looks like it could use a little leaning out to get closer to 12.8. I am running a stock AUJP bin. So. What type of numbers would be sufficient here? I want the car leaner down low than it is , but i want it to hit 12.5-12.8 AFR under WOT. Can someone point me in the right direction, and i mean give me an example of what you would set it to from 400 rpm to say about 3600. I also used VE master for the Ve tables below 3k rpm, I guess that is another story. Thanks.

Should hit the Tuning Guide Book sticky, chapter 5, '7730 ECM. Third link covers WOT commanded fueling. There are other good threads linked there too.
