Great news! Turns out my boost gauge isn't working. Drove the car today. I said hell with it and stepped on the gas pedal. Turns out I was releasing the gas peddal before boost kicked in(reason I thought the car was slow). OWNED/NOOB. Boost kicked in with boost gauge still reading -14psi. Z is in tip top shape. I guess it's time for aftermarket boost gauge! Thanks for all the help!
