What is the target a/f ratio on an OEM wideband to get max&a

[fantasy_blu_boi]

Hey there hondata, I just can't figure it out.
What is the target a/f ratio on an OEM wideband to get the maximum power out of my 08 civic si's top end??? 5000rpm+

I have injen cai/vibrant ... header/vibrant 2.5 in exhaust/stage 2 skunk2 cams with upgraded valvetrain/ported 69mm 06 tsx TB/portmatched RBC manifold. Currently running on the skunk2 stage 2 cams with i/h/e calibration map with just some added fuel on some parts of the fuel tables to have good part throttle driving.

If i add or minus fuel on the fuel tables for a/f ratio tuning on the flashpro, do I do the same adding or minus on the low fuel table as to high fuel table???
like when adding fuel from 5000+rpm to about 9000rpm, do i add on the low fuel map and the high fuel map or just the high fuel map?? this is for full throttle tuning.

any help would be greatly appreciated from an expert. I'm trying to learn to street tune this since somehow tuners in my area can't seem to get the car to run better or faster than I did with my own lil street tune. and they had a dyno too!

part throttle and wot tuning are completely separate. as far as I know, your target afr is the same as an na car without cams, so shoot for 12.8-13.2
