        Nothing fancy. Basic programmer for custom tunes. I wish they made a dash mount for these programmers.

        Easy to use

        This tuner is great allows you to correct for new tire size, change shift firmness to your liking and even bump your timing for a little more power! Love it! You can use this tuner. I made the changes in stages just to see what each one did it takes just a few minutes each time.

After you fill this out BAMA takes the information and loads the tunes into the tuner and sends it out to you ready to go. If you have not received the email feel free to call in and speak with BAMA directly and they will go through the questions with you.
