no biggie. i did the exact opposite. I took out the VCIS and left in the VTCS. I remember reading somewhere, (or we might have talked about it @ the shop) that the VTCS is more for cold starts. Who knows. Heck, get rid of them all. ha ha ha.
I'm not 100% sure, but I believe removing the VICS butterflies will negatively effect your low-end torque. Without VICS, the effective length of the intake runners is reduced which reduces the velocity of the air entering the cylinders. That reduction in velocity reduces swirl in the cylinder which results in shittier combustion.
It would be an interesting experiment for someone to rig their VICS so that it's permanently open and see if they notice any difference
