R32 GTR boost control,the factory setup is actually pretty good

before you go fitting a standalone boost controller, check that the factory boost control system is working properly. the stock twin turbo setup runs 10psi through solenoid-controlled wastegates. if the solenoids are stuck or the vacuum lines are cracked youll get erratic boost. replace all the vacuum lines with silicone, test each solenoid, and clean the boost control valve. a properly functioning factory system makes 206kw reliably. most of the boost problems i see are maintenance issues not hardware limitations.
