If I drop the OL from 80 I will start to get higher trims of course. I think I peak at about 22% now with it set to 80. I assume if I drop that to 70 I will start to get close to hitting the max fuel trims again.
Try dropping to 70 and then log. If it doesn't help then put it back to 80. I think there is a way with the PROcede to set target AFRs but I've never ran the PROcede so I can't tell you how to do it.
