Will I need a tune with a PT4000?

Did you do an idle reset? On a cold motor, pull PCM fuses, let it sit 15 minutes. Restart and allow the car to fully warm -up and relearn the idle. You go between park and gear a few times and that normally does it.
If that doesn't do it, you may need a little more idle air. A 1/2 turn (open) on the idle set screw is normally enough to fix that and not mess up the rest of the tune.
