Powerstroke Turbo Diesel Performance

Hey yall i have a 05 F250 powerstroke turbo diesel that i installed a banks 6 gun on. I really like the increase in power. I was wondering if its possible to adjust the turbo and, what kind of waste gate does it have? i never hear it blow off, does that mean it's automatic?

The 6.0l PSD doesn't have a waste gate it has a veriable geometery turbo so there is no need for one. As far as I know there are no real performance upgrades for the turbo yet either.
