tuning/safc question

[Mrdrd_Laser]

I just recently got a wideband and welded a bung in the downpipe so I can tune my car correctly. I am having to run insane correction on the safc to get the AFR somewhat reasonable. I'm shooting for about 11.5:1 at WOT. I've got all the low throttle settings at about 14.8:1 and the car runs great. The only question I have is why am I having to lean it out so much to get the AFR down to where I need it. I am almost at -25% correction at 7,000RPM. The car is throwing an 02 code as well. Could this be making my car run rich? I also have a 255 wally with the stock n/t FPR, could this be the problem.

Sorry for all the questions and thanks in advance
