Default Optimum A/F ratio target points for tunning

Hopefully getting a cobb AP shorlty, was curious as to what are the optimum target AF i should set. Not sure if this is how it works, my tunning knowledge is fair at best. My only concern is power, do not care about mpg what so ever. I f i didnt make sense, forgive me.....thnx

Just got the Uprev this week.
Do not have a tune for it.
Jnaut send me your tune for my car.
All i need is the tune for the engine as mines a 7 AT all i have in it now is the stock curve.
Still learning how to use it as I can only load tunes and waiting for Sam to send me the tunner program.
I may put the Cobb back on the car for the weekend at the track.

12:7.1 about optimum for the VQ on WOT,, little richer up top, I have run leaner with out any knock but could not monitor EGT's etc. TBH, I prefer to tune to rich power rather then lean.

Thats the thing jnaut, you can have two cars with the same mods and each will produce different results of the same tune, big reason why I dont run OTS maps.
When your fuel is right the difference in feel is amazing...
