Why won't my 550's lean out?

[ziggo0]

I'm having this odd problem with my MAFT. I finally got my wideband going and it pegs out at 10.0 rich at WOT, doesn't budge. Turbo is a 14b at 20psi, I have 550cc's correctly set via the MAFT and it was only turned lean enough via RPM mode to make boost cut stop. No knock and consistant timing. I went from -6% fuel pulled to -14% and it didn't budge. Tried upping the boost and it still would not move. Only other fuel mod is an evo 8 pump. I adjusted my injector size to be larger so it will pull more fuel globally, I went to -29% and it started at 10.0, went to maybe 10.5 then back to 10.0 at 24psi. How come my 550's aren't wanting to lean out?

maybe your 14b isn't pulling anymore air than what you had it set at and therefore wouldn't need anymore fuel.
