I have NO smoke on cold starts, NO misfires, or other issues.
My mods are in the signature with all maintenance completed except new injectors. 112k miles.
Can the turbo inlets fail or come loose after doing this tune?
Could the BOV make a whistle sound at low RPMS? I bought it and installed it without swapping spring or anything. I'm hitting and targeting 18-19psi.
Should I worry about the turbos?

Sounds like turbo siren, seems to happen to stock turbos when you get near 20psi, turbos could be dying worst case. Inlets popping off or some sort of boost leak can cause similar sounds too as mentioned.
Do you have any logs?
