Smoke Switch/VGT Turbo Question?

[SuperdutyKing]

This has had me curious as to wonder, when splice into the VGT harness and put a switch on it for smoke purposes. What does it do to the turbo, does it close the vanes or open the vanes all the way? It has had me wanting to know after i unplugged my turbo the other day and drove it down the once. It made all of like 8 lbs. of boost. So does anyone know the answer to this. Thanks in advance.

when you unplug the vgt solonoid it opens the vanes fully
