Do I need one solenoid for my electronic boost controller, or is two preferable?Updated 3 months ago

This question is best directed to the person doing the install and configuration of the electronic boost controller. In many cases, the primary consideration in answering this question is which option will allow for a greater reduction in the length of vacuum hose to be used. For most engine configurations with two banks and two wastegates, using dual solenoids would be recommended to allow for the quickest response and operation of the wastegates.
