Updated the tables with those values and also changed the boundary to 6.15. No change, maybe 1% richer, but it was bouncing from the afr values it was giving me before.
I also moved my wideband from my downpipe to bank 1 manifold. There was no variation from the values, so looks like I don't have any major exhaust leaks pre-turbo
Starting to think I'll just have to get a $400 high flow catalytic converter for my 4" down pipe lol.. I can't go anywhere without wreaking gasoline
