did you upgrade the turbo or is the turbo stock? Also does the bypass valve have any leaks???? Do you see a drop in power, it could mean that the valve is stuck or inoperable. Plus how many miles does your car have? It could be something as simple as an o2 sensor amid the valve upgrade.

let me know more information i would like to help you fix the problem.
