Any reason I should leave the BLM update amount set to the factory 2 in the TPI $8D? Which means the BLMs can only increment or decrement 2 units at a time, from 128 to 126 or 130...
Why not set it to '1' so it can go from 128 to 127 or 129 for finer fueling adjustments??

My BLM is at 129 at idle so mine will move in increments of one. So if it is seconds, why not have it update every second?

No, its BLM increments as I never see BLMs of say 127, 125, or 129, 131, always increments of 2 from 128.
I set the value to 1, now I see 127, 129, etc..
