2K RPM is fine while the engine is warming up. Really, keep the RPM below where the turbo begins to spool until the engine is starting to warm. This ensures warm oil is fed to the turbo before it begins working which just helps to keep it working as it should over the life of the car.
Once it's warm, it's good to kick it and take the engine up through the full rev range as this will make sure the turbo gets used and fresh, warm, filtered oil makes it way around flows everywhere it should.
