will a boost controller allow boost to go under the factory wastegate setting? for example, if i had a turbo where the factory wastegate was set at 10psi, would a boost controller allow me to go down to 5-6psi? also is a manual boost controller reliable? i have heard people say that they dont work well compared to an electronic boost controller.

NO

I perfer MBC over electronic, beacuse they are much cheaper. Ive never had a prob with mine.

Boost controllers only add boost. Your current psi becomes your baseline. I don't have one myself, but I've read that they can decrease the spool up time.

they do nothing to help spool up time

not entirely true. your wastegate starts to open up at a lower psi than what it is set for. with a boost controller, it will keep the wastegate from opening up until the desired psi is reached. so it does help spool up and boost response.

u get more boost creep with a manual boost controller. i just change my spring to a stiffer one and it helpped
