If you have one of our digital tuning box kits, these can easily be reprogrammed. Take the tuning box and remove the 4 torx bit screws on the back side. When you open the box, it will look like this: Plug in a printer to USB style cable to your PC computer. When this connects, it will open a new file folder window with a file called config.crp in it. Once you receive a new file from us, delete the current file so the container is empty. Then save the new file to this folder. Once saved, rename it to config.crp. That’s it your done!
