Flange leak on bank 2 is where I'd start but prob more to it than that.
Are the 02 switchpoints stock in the tune? Is the switching of the 02's lively? Swap them and see if the problem moves.
What do the sparkplugs look like? (Bad injectors?)

The switch points are stock, and they are lively. I am searching for a leak somehwere. The injectors are Trick Flow 60's. Another shop tuned this car and built it. So I am trying to fix it. LOL. The spark plugs are rich. Im gonna change them as soon as I can get the fuel trims closer together.

I had that when I had the o2 for bank 1 and the o2 for banks 2 hooked to the wrong banks.
My setup is a 356ci with a 260/268 (212/218 at .050 lift) duration cam with aluminium corvette heads and flat top pistons running 11.3 comp. ratio. with tuned port injection and vortec crank pick up and dizzy running a 411 pcm and 60lb bosch injectors, 1.6 ratio roller rockers. For transmission its a 4l65e built with the monster in a box mega ss kit. All in a 92 chevy ext cab 4x4 pickup with a 98 cab now installed with a third door! running only e85
Makes sense, it could go either way when chasing it's own tail. lol.

Yeah my truck in closed loop is one bank pos and the other negative by one or two percent. But when I did my tranny I got the two sensors switched and when it went closed one wnt -20's and the other +20's
