AFAIK boost cut is fuel cut. When you reach 14.7psi (boost limit) it cuts fuel.
Do you have twin dump pipes or FMIC? If so, these will be less of a restriction and will naturally increase boost. It should quite be 14.7psi but some engines are weird. My mates jzz30 that i mentioned ran about 11psi stock and close to 15psi with exhaust and FMIC.(no dump pipes)
