Do I have to put my serial number on my first order for tunes?

No. If you just purchased a device from AmericanMuscle.com you are not required to enter a serial number. This will be provided by our warehouse for programming.

NOTE: If you already have your tuner and are requesting a new tune or tune revision we cannot send our your tunes until you provided us with the serial number. If this information is missing and required, you will receive an email requesting the missing serial number.
