I did have a quick search, and i still couldnt find a perfect answer... Boost - mine is ~14psi with a MBC, and i had a friend say i would blow something up.... true or false? Just after an answer in black n white lol... Read here and there 12 from some, anything under boost cut from others whats the answer..? am i fine on 14psi? i have seen it spike to about 1bar, and hit fuel cut just over 1bar once, but turned it down a bit since then..
