I know that with a manual boost controller, you can raise the boost pressure, but can you lower it as well?

nope, you can only go as low as what the wastegate spring is set too. so say your wastegate spring is set at 8psi, you cannot go below that. But you can go higher then 8psi.

Ok cool. Thanks for clearing that up for me.
