pedalbox throttle responce gizmo

to be honest i've never noticed any delay from when i press the accelerator to the engine responding, so i don't see how this can improve on throttle responce. Looks convincing but i'm a little sceptical. If they gave me one for free i'd be willing to give it a go. I certainly can think of a better way to spend nearly £200, in fact my remap was only £200 and i'll bet there is a more noticeable difference with that than this box can give.
