With the amount of closed loop cells in the target AFR table. The trims will just bring it back to the target. If you want more fuel. Change the target table.
Here is something about fuel. Stoichiometric means that all fuel is burned. If all the fuel is burned and none is left over. You got as much BTU's out of the fuel that you can. Adding more fuel is not going to create more power. The same amount is going to be burned and that means you just have left over unburnt fuel. This extra fuel that is targeted at higher load settings is for thermal management and not because it creates more power. Where power can be discovered is mechanical leverage done by timing. So, adding a timing table that isn't set up for the cam isn't a great idea to bring out more power either.

Once I'm tuned and my VEs dialed in, I'll run open loop. I won't run 14.7 anywhere. 13.8 is the leanest I'll run at cruise. I could give a $h!+ about mpg.

Please don't confuse this as me saying 12.8-13.2 isn't what needs to be targeted at higher loads or WOT. I am stating that the power being produced isn't because the extra fuel is being burned. It is because the extra fuel is having a cooling affect. One big thing this cooling affects. Ignition advancement that we can now allow because we are controlling this heat.
Fuel = thermal management
Ignition = control over mechanical leverage
