Good call, I forgot to list that I have the 2nd gen Code 3. I'll edit the first post. Apparently, they labeled the C3 as a 65mm pulley because that's what it measures at the lip. The true dimension is where the belt rides.

For boost pressure, I was peaking at 17psi with the C3 on a boost gauge tapped into the Y-pipe (with stick manifolds and intake). Unfortunately, I'm changing so many other things now with the pulley I can't get a true comparison for people.
