5# Radix, what's a good AFR for WOT?

I agree with trever1t that 11.2~11.8 is safe. I called Magnuson several months back and spoke with their tuner and asked for WOT recommendations, he told me that they felt up to 12.1 was safe but no higher. Where is you WB o2 sensor mtd.? I would be concerned with your WB calibration because It seems that with a 13.9 WOT afr your motor should have by now.

Hey guys, the PLX brand wideband reads about 14.68 at idle, so I think it's accurate. It's mounted on bank 1 just before the transmission cross member. I did some VE and PE tuning the night after I posted this and got the AFR into the high 11s. It needed a bit more tweaking but my laptop ran out of juice. Apparently the tuning made a big difference, because on the way home I did a 20 punch and broke my ring and pinion.
Please tell me if I am interpreting this correctly: Since I have the stock map sensor, the bottom row of the VE table is going to be hit at any amount of boost, whether 1# or 5#. So the bottom row is going to have much higher numbers than the row above it, correct?
Also, thanks for the tips. Next I'll work on the timing. I'm only running 15* at the moment. What do you guys recommend?
And I guess this shows the 6.0 is pretty stout if it stood up to my botched tune for 6 months.

Well yes an no, your MAF determines the majority of your fueling past 4k rpm. You need to tune your MAF table for WO throttle. You should set up a Error histogram for your MAF table so it tells you how far you need to scale it to get the correct fueling. Do you have HPT or EFI live?

Alright, I was thinking the MAF was disregarded during power enrichment. I logged the MAF that day, but the errors were only 1-3 % or so, so I just left it alone. When I fixed the VE table, my AFR went to the proper range. When I get the new gears put in, I'll check it again to be safe. So 15* is low timing? What do you think I could raise it to? I have HPTuners. I also have a cammed 6.0 with a 2.9 pulley, so I'm not going to get much more boost out of it than the 5 or 6# I'm making now. I could go to a 2.8 down the road, but it's plenty fast for me right now, just want to get the most out of it now.
