Have you done anything to the exhaust or the intake? The recommended boost level for stock turbo's after the basic mods was 12 to 15 psi. I saw that in an earlier post a few weeks ago. But before you do that make sure to get a boost guage. Stock turbo DSM's run about 9 psi I was told. I believe you are a 2G so the stock BoV is plastic and leaks around 7-9 psi. Replace with a 1g BoV or an aftermarket.
Good luck!!
