The battery voltage offset and B4005 is added on top of that. So, I'd drop the min IPW's down to 0.8 or so. Pull enough out of the battery voltage offset table and the AFR's should lean out. A little richer down low isn't such a bad thing though. Too lean, and you'll get some fun cam surge/bucking.
**JUST REMEMBER** the battery voltage offset table is in MANVAC - not MAP. So, when MAP is low, MANVAC is high. For me, 30kPa MAP = ~70kPa MANVAC because of the altitude I live at.
