Sounds like you might be missing a few parts.
The Powershot uses boost pressure to regulate and control the regulator and picks it up from the MAP sensor.
The BD kit, taps into the intake to pickup air flow which is what opens and closes their particular regulator. They have made some changes to them and they now also route thru the heater hoses, so the best bet is to call Bully Dog so you get it done the right and safe way.
