Thank you for the Tech support, it's really helpful so far!

About VDI: Will the VDI valve work fine if I just leave the vaccum diaphragm unconnected? Or is no vaccum for low end? I know it turns on at 5000 rpm, but what do I do to make sure it's in the proper place on the intake?

What I'm trying to say, is that if I dont make the vdi valve work again, wont it be in the "closed positon" and rob hi rpm power? or does it "close" at 5000 and up? I'm confused.

PS: It seems like the VDI valve of the middle intake is identical to the "roller ITB valve" setup where instead of pancake shaped butterfiles, you have a tubular roller that twists to open and close airflow.
