I've known guys to blow it with stock boost... It's a crap shoot.

It's the biggest restriction in your intake system as far as I'm concerned so I would swap it for an aftermarket one. The stock one just isn't that awesome at cooling more psi of air than it was designed to handle.

Ya but what's your timing? You could have 18.5psi but crap timing and not making a whole lot of power. Your really boarder line there. My tuner wouldn't go over 17psi
