A single bad injector would not cause this.
Its not throttling up, which would seem to indicate a fuel issue, because Diesels are fuel throttled (no fuel, no increase in RPM).
I would start by checking your fuel pressure. You need to see a minimum of 45psi at all times. If it makes 45psi then fuel pressure isn't your issue. If it doesn't then the issue could be a bad regulator spring, in which case its time for the blue spring kit. It could also be a bad pump. They don't fail often, but it does happen.
As far as a turbo issue, that could cause a fueling issue because the two systems are linked electronically. When you press the accelerator does boost rise? If not something's wrong in the turbo system.
Check those things and report back.
