Turbo Sound

I have a H&S Tuner and I'm DPF deleted with EGR disconnected. Also running an S&B CAI. Right after I installed this set up my turbo has more of a screech sound then a nice whistle while spooling up. Mostly between 5-15psi. That's with normal driving. Anyone else have a whistle that's closer to a screech noise? Its only on acceleration, performance has been great when I want it but the screech is annoying.
Power is nice, love the exhaust note and diesel smell. My mpg has gone up by 3 on the hiway. I don't flog my truck at all, I did this for better mileage and it is my work truck so it needs to be reliable.
The main reason I went with a tune to start with was because FORD in all their cheapness wouldn't replace my DEF pump that failed,,,not covered under my drivetrain warranty(bumper to bumper is expired). So I decided they weren't getting anymore of my money and I would just tune out that garbage.
I would be worried my turbo was about to fail if this screeching started weeks after the mods were done, but it was immediately after that it started. Since I own an early 2011 the turbos aren't great to begin with, maybe I should be looking for an aftermarket turbo soon to cure that noise.

I have the same parts as you and the same screech is heard by all. Basically it seems to be the wastegate opening and dumping excess pressure into the exhaust all at once, and since we're running straight pipes it sounds bad.

FYI
Friday night I blew up my turbo. I'll be calling a lot of people Monday to confirm and start seeing what I can do to fix it better. Probably too much boost, I set my defuel level at 31 psi.

I hear the big woosh that's very noticeable when the boost bleeds off, I assumed that's the wastegate and it sounds cool. But this screetch I hear while spooling up is horrid. Makes me worry slightly, especially with the 2011 turbo. Im going to order a confederate real soon, for some piece of mind. Cheers

Forgot to post a reply about what I found. Turned out it was the metal gasket burnt out under the EGR block off plate, it was making the screetching noise as a small amount of exhaust came out into engine compartment. After breaking off bolts in the manifold while removing EGR crossover I guess I was a bit hesitant to tighten plate as much as I should have.
New gasket and bolts tightened good, problem solved.
