Sometimes it went into overboost, when the vanes didn't open up. The electronic actuator / wastegate is controlled by the engine’s ECU and is used to efficiently regulate the flow of the turbocharger and deliver precise amounts of turbo boost pressure. Its purpose is to slightly advance or retard the timing of when the camshaft opens or closes the intake and/or exhaust valves. Anyway I've freed up the wastegate, which to be honest wasn't that sticky, so perhaps the actuator might be faulty.
