I found a sticker in my glove box of my new ss n says super chips equipped how I tell if it does

 

Well take the sticker out of the car. If you go to the dealer for any warranty work, they "could" deny repairs because of the Superchips install.
Not saying they will, but why take a chance.
As far as how to tell: If it boosts over the stock 14-17lb range, then it most likely has been installed.

 

I got aftermarket warranty from dealer just got car a week ago n I hit 19 lbs

 

if you hit 19psi you most likely have the superchips tune installed...who ever traded it in must have had it and it never got reflashed...the tuner voids the warranty so i would talk to the dealer on that one...unless you dont mind the extra boost
