I just bought some et streets do i need to change anything to my chip

 

You could have the gear ratio changed to gear ratio that you will be running with the slicks, I guess you would need a flip chip on for strretand then strip mode. I belive you can have this done i think that you would need to have it done unless you want you speedo/tac inaccurate. Someone correct me if im wrong. I belive Sal change change to any gear ratio you need.
