or is that just for s/c'd?

Only for S/C from what I heard. It gives turbo applications a little less parasitic loss and a little better throttle response with a couple of ponies added. The throttle response isn't as good as say a lighter flywheel or TB, but it'll help.

Yea, with a S/C, the UDP would reduce boost because the charger is being driven by the pullies. With a turbo, Oscar's response says it all.

When I had my S/C installed, I had to remove my UDP. I could feel the difference in the throttle response.
