One thing I left out before you start raising the boost is a boost gauge. I used an Auto Meter

AGP wga
AGP Turbochargers, Inc. :: SRT-4 :: Boost Control/WGA :: SRT-4 Wastegate Actuator Kit

It says SRT-4, but you'll find a lot of the parts are interchangeable with the PT turbo.

This is the DSBC I used.
