I initially had the tune in the cruise button, but the tune is on all the time and to turn it off you have to press the cruise on and it turns off the tune and turn on the cruise control. It was cool being able to press a button on the steering wheel, but the big issue for me with this was that I had to go into the dealer for a tranny issue and if I pressed the cruise button to turn off the tune the cruise light would be on. I thought if the tech was to see the cruise light on he would hit the button to turn of the cruise causing the tune to be ON. If this happened and he took my SS for a tranny road test he would snap is neck being that he would not be expecting the big surge of POWER and next thing he would know something was up, but he wouldn’t know what happened because the tune is stealth. I decided to have it switched to the T/C button because I didn’t want to see anyone who didn’t know about the tune hurt or have them wreck my ride.

I’m not sure if they can do other buttons.
