squeal under acceleration!!!Help

I have a 08 F350 6.4 and just did the tuner dpf delete and dual flo pro exhaust and now i have a VERY high pitched squeal coming from somewhere!!! It only does it when I accelerate and around 2500 rpm.....when it starts you let off a bit and it goes away...what could that be?

Mine does the same thing sometimes, almost sounds like one of the turbos, like maybe the VGT actuating? I think i'm going to rebuild my turbos soon if they're still in decent shape.

Mine used to make that noise at the same rpms(2300-2450) before I Deleted. Since then, I haven't heard it once.

COuld be the pipe, OR it also very would could be the Degas bottle cap... I know my buddies was doing that and I told him that they are all crap caps and ford has a new design out. He went and bought one and it has a much stiffer spring and it keeps the needed pressure in the system, and voila no more noise.
You can buy a Stant one for 5 bucks at Advance Auto or its 13.99 from Ford.
Try that, either way u should change the cap anyways.
