I've heard of "overclocking" a computer's processor where you feed it more electricity, make it work faster and also attach a bigger/better fan to it to stop it overheating. We might need some context : what exactly do you mean by overboost?

Sorry, perhaps I should have asked: What is Overboost in relation to common-rail injection diesel engines, ie the Citro�n Xsara Picasso? It's mentioned in Citro�n's TV ads.
