AFR was supposedly around 12. Not sure how running lean would put more fuel in the cats but the exhaust will certainly be hotter and can cause them to melt. I damaged two passenger side cats (core separated from outer casing) before the driver side cat melted.
The risk of a clogged cat or shrapnel shooting through a turbo at WOT is too high for me going forward.
