Here's the combo:
TEA S2.5 massaged by craig gallant flow 317cfm @ 600
232/238 XER 111lsa 111ICL
All the bolt-ons. Last year the car went high 10s on pump gas. I finally got my hands on a wideband O2 and the car read 11.8:1 - 12.0:1 from 3k to 7k. How much power is to be gained by leaning the car out?

Quite a bit. I gained 12rwhp by going from 11.1 to 11.6

Your right answer might lie between the two.
At any given AFR the timing needs to be re-
optimized to get the most out of it. You might
try hitting 12.5, 12.8 and 13.0 and tweak up
timing for each case, let the dyno decide.
Then tell us....

Phil take her to the track and lean out our every coupel passes till it doesnt gain, or its leaner then you like. maybe try throwing soem timing in it the pass before you lean it out soem too to see if it rather be richer with more timing (tight lsa cams ive worked with seem to respond to that)

I think you are fine, but you could try leaning it out to 12.5:1 AF but no leaner, you want the motor to live and not get pulled in two months.
