As with any mechanical part failure is always an option.Take the line off the acutator and go for a spin. This should keep it closed and you should build boost beause it will not open. If this is the case get a new actuator. I don't run one on my truck becuase I put a van turbo on it, but the van turbo has a larger exhaust housing so over boosting is not as much of an issue.
