I am currently running dp,cb (straight pipe, no exhaust), and bcc. I am hitting 20 psi on 4th gear runs in cold weather. I want to limit my boost to 18psi. Will a mbc be able to limit my boost to anywhere from 14-18psi even though I am running 20 psi with no bleeder T or anything. Or do I need an ebc for that? I'm under the impression that an mbc can only increase your boost from stock (in my case 20psi) settings.
