If the air/fuel mix and boost timming retard is right you can run up to 15psi on the fatory motor.

To change the boost pressure produced by a turbo you need to adjust the wastegate. That means you can go from everything from a one-way valve from home depot, to a $700 Apex´i AVC-R.

Right now I´m going to be using a simple valve, but planning on upgrading to a TurboXs 2 setting boost controller.
