ESS SC and under drive pulley

I am about to install a ESS VT2-625 do you have to remove the under-drive pulley for it to work correctly? I.e. Get the appropriate boost pressure of 7 psi!

Yea, underdrive pullies don't work with the superchargers since they have there own pulley system from what I understand

Yes, you remove the under drive pulley. That's why you see a lot of them for sale here because those people went FI.
