ETC Area Scalar ajustment...
I have been logging my Mass Air Flow (lb/min) and Idle Desired Air (lb/min) since I installed my FAST 90 and ported LS2-TB. My Idle Desired Air is always .2 - .24 lower than my Mass Air Flow.
I have not messed with these settings but I take it I need to raise my ETC Area Scalar by the percentage difference???
Here is a JPG of the histogram

Check your LTITs and STITs. If they're reasonable I would leave it at 0.0255.
My NW 90mm TB works best at .0320 (2001 C5) - but that has to do with how the TB was setup by Nick Williams. Mine was a very early TB setup by Nick. Later TBs were setup to work with the .0255/stock value.
FWIW.
