It sounds like it's over boosting, the wastegate might not be opening or a pipe has come off the turbo or actuator from the amel valve.

I would of thought the same on a pipe coming off. Mine did exactly the same and all it was is the pipe had come off the back of my boost gauge.

Hopefully a quick cheap fix
