Profec B & MBC

[SOURCE1064]

I have a question about whether it's worth getting a MBC in addition to my Profec B. For some reason I think I heard that the Profec B doesn't hold boost well over 25 psi. If this is the case would it be worth getting a MBC to use when I go to the track and want to crank the boost up all the way?

Thanks,
