WOT A/F Ratio

[comporange04GT]

I just got my car tuned and it runs great and makes great power. The only thing I am wondering about is the A/F ratio averages about 12.5 at WOT. Is this a little on the rich side? I want a safe tune but I use the car as a touring car so fuel milage is a small concern.

No, a little on the lean side.

N/A you should be between 12.5 to 13.0 WOT for a safe tune. you can go up to 13.5 but that's pushing it. i'd aim for 13.0.

No, a little on the lean side.

you are wrong.

Little rich, but your only throwing away a few HP...not bad and the car will run cooler.
