So I finally went around and got the AEM UEGO wideband on my car today.

I'm running 

14.7 at idle

14.5 at light cruise

13.5 on light acceleration

and 13-13.8 on full WOT.

I also only get 12-13 psi in boost with the stock restrictor removed and full breather mods. I also have an issue where my car jerks when my fuel tank gets below half a tank.

Tomei fuel pump was put in about a year ago..

What I've ready online leads me to believe that I'm running way too lean on WOT. 

What should I start checking first?

Take it to a workshop and get a trusted AFR meter stuffed up the tailpipe. You never trust a fresh install unless it matches something else that you trust.

As to the boost.....~13 psi is what you'd expect. Maybe a bit more.

As to the jerking. You need to run it with a fuel pressure gauge plumbed in and see what that says when it is playing up.
