The fastest stock block DE is running 11.7ish AF/R for tune

Low 11s is optimal and anything 12.2 and over is bad, period.

Instead of going aggressive tune, may be better to just bump psi.

(Highest HP stock HR that I know of is running low 11s) ((see what I did there))

A lot of people dont join forums or post things so we'll probably never know.

well, it's perplexing the people who are hermits about their builds. Even all the sweet builds you see on fb, then shows like Z Nats noone shows out.

Yeap... with FI 11.8AFR is the magic number. I'd never tune bellow 11.2 or above 12 to be safe yet efficient. Anything below 11.2 is just wasting gas and power.

My car maintains at 11.75AFR average throughout the whole pull on WOT.
