If there is no hose on the actuator then the waste gate will stay closed and you will boost until the turbo over speeds and destroys itself along with the engine! lol
Sounds like a boost leak, the actuator springs is weak, or you do not have enough pre-load?

See here if you are unsure of how to set the correct pre-load...
