Overboost protection VS Fuel Cut

[Zazzn]

Can someone explain the difference between overboost protection in the black vs fuel cut. Other than allowing the boost to be over the a threshold for a specific time before cut, whats the point of using the over boost protection rather than just setting the fuel cut in the fueling - fuel cut menu?

When you use maps/boost switch for different fuels or flexfuel setup, you may want different fuel cut level. With overboost protection you have it always right, as it tied directly to boost target.
