Some
or is it closer to the "2000" rpm cell.
Mostly.

Some
or

Yes, the 90 should be used also, and more of the change should be made to this cell.

Remember that the engien is dynamic, that is, it's always in a state of change.  You need to "spread out" the tune.  If you need to change things at 1800 and 85 kPa, and you only adjust the 90 kPa and 2000 rpm cell, then you may affect fuel (or spark) at 93 kPa and 2100 rpm in a negative way.
