Whats the lowest boost setting a hallman mbc will go?

 

Depends on your wastegate spring. Turning your controller down all the way allow all pressure to go to the wastegate without interruption, so it becomes whatever the wastegate spring is (in my case ~14psi). Turning the boost controller up interrupts the pressure getting to the spring, causing a delayed opening of the wastegate, allowing higher boost.

 

On my VIII, the stock wastegate pressure is 12.

 

How does everyone feel about the cockpit adjustment you can get with it?
