12.8-13.2 at WOT for a n/a car
12 is a decent number for a supercharged car

40 psi is a good number for a fuel pressure.

a wide band is pretty much the same thing a dyno uses to measure your a/f ratio. gives you a read out in actual numbers. an autometer type one only gives you a generally idea. red=lean, green=rich...not too accurate.

If by chance (heck, I believe you will ) you see a nasty lean spike when nailing the skinny pedal from cruise to wot .........

You can knock it down with the manifold scalar

Start off by reducing the value by one full point and ajdust to your satisfaction
