The last 6 digits do not match my VIN...Updated 2 years ago

The last 6 digits of your VIN and the name of the tune file have nothing to do with your EFI LIVE tune. Some other companies name their tune files this way, I believe one of the videos we send in our instructions you states this. However, we name these different.

The tune file is named based on the truck you have and our EFI LIVE tune order number. Our techs use this number to organize customers tunes and be able to reference them easier.
