First you dont need a tuner. Many shops will have a chip that they can program. I didnt want to get a tuner because i chose the dial. That way i dont have to turn of my car load a different tune when im trying to race some one. All i need to do is turn a dial and i can toggle between tunes.

 

Mine has an excellent street tune & race tune (track only - race fuel)! ....no need to change anything on the streets! lol

 

You can change the dial while driving?? I wish I had known that lol.

 

Yup. When ever i want.
