Sounds to me like your turbo is out. Any loss in performance?

I'd say something to do air induction. CP or turbo

Need to remove the Bubb Rubb whistle tips.

Seriously, my guess would be boost leaking somewhere or (less likely and much worse) turbo bearings. DPs frequently exacerbate existing issues, and can create new ones when you crank up the boost. I'd put a mic underhood or have someone listen with the hood open while you load up the engine against the brakes to locate the source.

Maybe o2 sensors are not fully seated?
