those codes are in regard to a boost leak and underboost. anyone have boost leak/ underboost issue?



Check all vacuum lines ensure they are pliable and look perfect if not change them. Check your charge pipe and intercooler connections to ensure they are tight and pressure test if yu have shop air. Check factory diverter valves(Likely culprit) to ensure they are working properly. If all these are correct it is turbo related and usually wastegates/actuators.
