Here’s How It Works…
Once you place your purchase we will send you the necessary tuning hardware (Black Box Device)
Once your Black Box hardware arrives you will be required to take a stock read of your truck’s ECM and then send the file it in to us.
Once we receive your stock file we will begin the tuning process (Which takes about 1 business day)
Your custom tune will then be emailed to you
With your tune file in hand, you will then be ready to download it onto your Black Box Device and flash the file on to your vehicle
