That's where I don't have quite the understanding to answer your question. I'm not exactly sure how it controls boost. I think it has to do with the throttle mapping. With the MBC, in conjunction with the Si-Drive, the throttle mapping would still be changing, but your peak boost would be set by the MBC. I think this would be a better question for your tuner.
