Hey blackonblackdub, they are many factors which determin the amount of boost you are running on the stock turbo. Factors range from air temperature, humidity, and even ecu programing. The best way to see what your particular car is boosting is to mock up a boost gauge and see it for your self.blackonblackdub said:how much psi is running on stock turbo
I have heard stock GTI MKV boosting from 8lbs upto 13lbs, the only difference is where they live. Elevation of your city can also cause fluctuation in the amount of boost you are getting.
