Question Some input for AFR at WOT

just recently installed a AEM uego wideband and installed it in the B2S1 location and because of that im running an Open-Loop Tune. i read the passenger side reads richer than the driver side so i was thinking about running a bit richer to compensate the driver side. currently at WOT the afr reads 12.6-12.7 and the pcm has a commanded AFR of 12.4 at 27-28* of timing.

my question is should i shoot for 12.4 or just stay at the 12.6-12.7 or/and increase timing to 29/30*?

right now its on stock manifolds. only mods right now is LID and catback exhaust.

What type of fuel are you using? Straight gas, ethanol blend?

Stick with ~12.8 and find a good amount of timing that doesn't knock at that AFR.
