Welcome to the forum!
I would remove the intake boot from the breather to turbo compressor and inspect the blades. If the boot is the original orange boot, make sure it is not tearing at the clamps (common). Ford has a kit to update that boot and there are a couple of aftermarket replacements as well (orange boot is not available anymore, hasn't been for a long time). Also check the radial play and axial play of the turbo shaft (maybe the blades are starting to hit the housing???). The turbos can be rebuilt. Ron's Turbo Service
has rebuild kits and I'm sure there are other places that sell them too. The SC 1705 shouldn't have produced enough extra boost to cause turbo failure. Cheers!
