I had to still crank the boost controller a few more turns to get to around 21 psi, but I gained all my lowend back and lost minimal topend from the feel of things. I would port your stocker w/ a Dremel as it is pretty easy and put it back on as it is much more durable and won't crack. You can also tap your stocker for an EGT probe.
