I have a wideband and at WOT I am getting 11.9 to 12.1 AFR. Wouldn't it be a waste to go with an enrichment Module? I feel like I already need to lean it out.

All too often people think adding more fuel will give you more power. Then comes the wideband sensor only to prove them wrong. I would not add more fuel since it's already good enough. You do want the mixture richer at full throttle than part/light throttle.

The thing to check is if a rich mixture at WOT is held at a;; RPM levels. But yes, 12:1 is definitely enough.

Thank you! I am usually high 11s and sometimes low 12s so I was actually thinking about leaning it out a bit but I see everyone with this mod and I was starting to question my own understanding of the topic. Thanks again!
