If you're not using TEMS it's a waste of space, IMO. I'd sooner put in a digital volt meter/AFR display/Oil temp display in the space. If you want a light show for the sake of a light show put in a LED bar and wire it up to show your throttle percentage.... Otherwise it's like shoving crazy, old grandpa in the back seat and giving him a steering wheel and letting him shout "BEEP, BEEP" once in a while just because you hadn't the heart to leave him at home when running to the store.
