It's been suggested to me by Roman that the best (easiest?) way to do it is get two dyno pulls... one with them open. One with them closed.
Then overlay the graphs and figure out what works best for your particular combination.

I will say, I have no VICS or VTCS so I'm only passing along what I got during my quick and dirty presentation while at his shop.
Oh, and he also confirmed what many folks have already said... even with whatever butterfly removal/porting/etc. on the VICS manifold, it won't come close to an off-the-shelf squaretop.

the way people were porting and removing butterflies makes little sense, so yeah, that's to be expected.

but no one has actually done the modification that I want to see dynoed.

It's too cheap and easy to upgrade to the hawnduhh setup to mess with this
Although I do appreciate the squaretop for being OEM and fitting perfectly and requiring nothing
