One possible cause could be a faulty wastegate or diverter valve. It's important to have these parts inspected and replaced if necessary to maintain proper boost pressure.

D

Another possible cause could be a leak in the intercooler piping or a clogged air filter. These issues can restrict airflow and result in decreased boost. Regular maintenance and inspections can help prevent these issues.

S

It could also be caused by a malfunctioning boost pressure sensor or a vacuum leak in the system. These issues can be diagnosed and repaired by a certified mechanic with the right tools and expertise.
