Do Fiesta RSTs have a limp mode because mine will not rev past 3k rpm? Also There is no pipe coming from the actuator so I'm baffled as to why it isn't over boosting let alone no boost at all. There was quite a bit of preload in the actuator rod when I checked and the turbo bearings are fine? Checked pipework for leaks and there was no damage that I could see. Help me solve this mystery please!
