you might get better fueling resolution by changing the map axis values so you have more which are under 101kpa than above it.

maybe 30/45/55/65/75/85/95/100/140/170/200/250 or something like that.. most driving is done in lower kpa map value regions and the change in fueling requirements is more pronounced in those areas than under boost conditions.

of course, it you are only using the AFR table in Tuner Studio a reference (rather than "Incorporate AFR Table") its academic but it still makes sense to use the same axis values as those in the Fuel VE Table 1 otherwise it can get confusing
