Adding fuel with a VAFC is a no go:

use a FPR to add fuel then take it out as needed.

fyi.. on my 'stock' ITR no fuel was added while on the dyno.

You can add fuel depending upon where it is on the curve and what the MAP signal is at that point, but as others have said, you should have a FPR to raise fuel pressure, then lean out where necessary.
