Nah not really, they do increase the efficiency by shutting off 4 of the 8 inlet ports at low rpm/boost to increase the velocity of the intake charge and give better swirl thus better mix, cleaner burn and more power/economy but I don't reckon I drive that slowly often enough for it to be worth the mind f*ck of trying to control them opening and closing at the right times.
