if you have more than one tach, its rice.

if your car doesnt already have a tach, then its fine to have one IMO. but if you notice most race cars take out all guages, including the speedo, and only have a monster tach, thats fine. in my car, i swapped the engine, the new engine has a higher redline than the old engine, i could have put in a monster tach, but instead i put a single shift light and pill to reduce the rice factor. and yes, a big ass tach in a subaru is rice, your car already has a tach in front of your face, why have two? two tachs is rice, buy a shift light. you know they sell shift lights with out the tach right?
