You cannot turn down the boost on the the waste gate spring.
EXAMPLE: If you have a 8psi waste gate spring, the lowest you can turn the boost down with a boost controller is 8psi. However, you can add pressure to that waste gate with a boost controller, you just cannot go lower than what the waste gate is set to. Also you do not want to go too much higher than the stock either. If you have 8psi spring and plan to boost up to 30psi all the time, you will have issues holding that boost. Not that any of us will be boosting to 30psi except "maybe" Bullitt, lol.
