So my AEM wb reads 10 flat at WOT while my O2's are running around .94 -.96.
Both O2s and WB have been in the car for at most 6k miles. I also have a snow performance w/m kit installed (625ml/min) on the car that uses a progressive style controller. Now with the w/m, I should be able to run a little bit more of an aggressive AFR than a 10 flat. I just don't know if I should believe the nb o2's or the wb.
Trying to lean it out a little did show small traces of knock. Not enough to pull timing or anything but still something I'm not very comfortable with. I do have a high mileage car which is a factor I consider before getting too aggressive. Any thoughts on this at all?
