Thread: How to read the AFR on wideband?

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?

Because if you back off on the fueling now you'll start getting more knock.
