I get about the same boost taper that you do - boost drops about 1.5psi between 4000 RPM and 7000 RPM. I've been told that an EWG would fix that, but it doesn't really bother me.

I am running the IWG actuator that came with the turbo. If I remember right, I get 12psi with the MBC turned all the way out (min boost). But it's been a long time since I actually checked.
Its not my map sensor. My boost gauge reads 22 psi as well as my netbook with the actuator wired shut. ATP is really leaning on the inlet not being a 3"

What inlet do you have NSFW?
