I would say that most folks shoot for AFR at WOT between 12.8 and 13.2. Where you get the most power will depend on your specific set up and engine, but this is the range that you want to be shooting for.
Increasing the K value in your bin will richen your mixture across the board as will increasing fuel pressure. But, within reason, your closed loop feature will mitigate the richening in the closed loop portion of the fuel map.
Richening the last 3 (high load) columns of the fuel map will add fuel at WOT.
The general approach that I take is to turn off closed loop feature and then adjust K to get light throttle and idle close to 14.7. Then turn closed loop back on and fine tune WOT with the last 3 columns of the fuel map.
