Sometimes you can hear if your car is leaking boost and since you are stock you should notice any abnormal sounds from the engine bay as you would not be hearing much if any turbo noise with stock dp's/exhaust/intake, etc. Do you have a diagnostics tool like the Bavarian Technic cable? You can then log to see if hitting boost targets and scan your car for codes. With boost leak sometimes no codes (30ff) thrown so you need to do a pressure test for that.. hope this helps.
