I was under the impression VQs are better off running ~12.5:1 mixture, as opposed to anything leaner. And that factory is a bit lean with 14s in the low-end and mid to make the car more fuel efficient...but tuning it to a mixture around 12s adds considerably more power down low, thus making the car more aggressive in every day driving. It only hits 11s and 12s under WOT when you're approaching redline. Anything below the 5500RPM mark, and you're around 15s 2-3K RPM, 14s 3-4K RPM, and 13s 4-5K RPM.

If that is not the case, then why does nearly every dyno chart and tuner strive to hit an AFR in the 12s for VQs? I'm not trying to be an ***, btw...I'm legitimately curious.
