Hello everyone. I was just thinking.. how do people regulate their boost to as low as 0.3bar-0.4bar? by using external wastegates? from what i read from some American forums, they use an external wastegate with a 7psi spring. what does that mean? if i'm not wrong, manual boost controllers can only increase boost right?
