Due to EPA regulations we do not provide any tuning and have not for a very long time.
If you have a legacy autocal that you would like to have unlinked, please enter the serial number of the autocal (located on the back) and we will process the unlink code for you.
This will allow you to take the autocal to the tuner of your choice and will still leave the vin licenses attached to the truck.
