What does a vette servo do? help/hurt trany?

Hey guys, I was curious what a corvette servo does for a stock 4L60e transmission.

Does it make it shift tighter/harder? Can this wear down the clutch plates? I assume a tune is needed for one?

It has a little bit bigger piston for the second gear engagement band so it applies a little more force when you shift into second. Makes the shift a little firmer and gives a little more holding power in second gear. No tune is need for it.
