Figured it out... For some reason I need the valve backed out further then recommended. I'm at eleven turns out for 14psi
I had initially switched mine, too, and thought the further in I screwed it, the lower the boost would be. I kept overboosting to 18psi. Mine is fairly far backed out to get 12 psi, but each rotation in adds about 2 psi. ;)
I love the difference the gillis valve makes in driveability, though. The on/off switch is much lower in the power band. :D
