Then one of two things: In your two weeks of driving, you're not on full boost often enough to open the WG and "dirty up" the pipe....or, you're running too lean on boost and don't have any unburned fuel left to coat the pipe with carbon.

As I said earlier, if the WG is not opening then you have to ask yourself where that boost is leaking out at. Even the old stock 3LDZ turbos will overboost without a functioning WG.
