the Z is built and tuned with spirited driving in mind hence there not being a sports mode button. it's tuned from factory to go go go.

you can however as I stated before have the line pressure tuned to make the AT shift even harder. I recommend it to anyone who gets their Z tuned since most don't know its an option with uprev or ecutek.
