So keep yourself optimal both in hardware and software with this SCT BDX Tuner. Its superior tech will marry with your Sierra’s and bring about a marriage of horsepower and brainpower.

      All the Tunes You’ll Ever Need. No, not music. Tunes that help your powertrain run better. Configurations that improve gas mileage, overall torque, and many other things. This tuner downloads custom tunes from SCT’s cloud and will save your custom and favorite tunes to it to keep you running just the way you want.

      Installation. This installs rather easily, putting in the simple cable to your Sierra’s port, and then attaching the other port into a computer. You will also need a WiFi connection, so you can get the tunes you need. Allow about a half hour for install.

      One-Year Warranty. SCT provides a one-year warranty, protecting against manufacturer's and material defects.

          They had the product I wanted and confirmed fitment with my truck. The price was great and had free 2-day shipping. So far very happy and will shop here again in the future.
