2011 gmc sierra 5.3 e38 supercharged which VVE table???
I am having issues with a getting this truck to fire up and idle after doing a cam swap.
what VVE table actually affects fueling as the engine returns to idle or after a rev in neutral?
IMTV open? Closed?
what determines whether to use the 2bar/3bar tables?

Are you running MAF-less (SD), if so, are you getting an immediate MAF DTC...?
What MAP sensor do you have (2-bar, 2.5-bar, 3-bar), did you set the MAP scaler/offset...?
The 1-bar, 2-bar, 3-bar VVE tables occupy the same space, the coefficients you generate from the particular VVE table is what the ECM uses... so if you have a 2-bar MAP sensor and you edited the 2-bar VVE table, and generated coefficients from that, and are running a 2-bar MAP sensor with correct scaler/offset, then the ECM is using the coefficients generated from that.
IMTV Open if none exists (actually, some people populate both tables IMTV Open and IMTV Closed with copy/paste).
