I have been having a little trouble setting my mbc to the levels I want it. Yesterday it would hit perfectly at what I want it (about 15.5) and last night it would spike in 3rd or fourth at about 16.5-17!! Is this bc of weather or what? I have turboback, stage 0, and a couple other mods. Does the unichip regulate boost??? Sorry for all the questions, I am just kind of at a loss here. If this is normal, spikes aren't safe are they?
