Best thing to do is learn when it hit's,mine use to hit about 5.5k in the rev's so just befor 5k i would let off or change gear..
Hitting fuel cut will cause damge in the long run, (dont quote me on this i could be wrong) but when you hit fuel cut it basicly shut's off all injector's for a sec, then puts them back on cuasing fuel surge thats when you get the big jurk in car...
