How to read the AFR on wideband?

Hey guys, im still trying to figure my AEM wideband out.
To scan the AFR, do i scan going from WOT?
Or will it be the same doing a scan from let say 60mph?
I went WOT this morning and it read 10.4-10.5.
And rolling it read 10.9 then it went down to 10.5.
Any input is appreciated!
 


WOT is the value youre most concerned about.

youre still running really rich. i think you need to back off a pulley size and lean the car WAY out. it will feel much faster running on a better AFR.

your AFR at WOT should be in the mid 11s. even with my meth i still only hit 11.0.

If you dont mind me asking, why back off a pulley size to work on my AFR?:th_scratchhead:
 
you need less pulley and less fuel. once your fueling is dialed in THEN try to bump back down to where you were and add a little fuel.

youre running stupid, pig rich right now.
