When you install a Chip, module, or Programmer, your 2020-2023 GM Silverado/Sierra 2500HD/3500HD will produce more horsepower and torque. Performance Chip were the most common way to modify the programming at the dawn of the diesel performance craze but is now done by hand held programmers. Dash-mounted tuners improve power and performance while also allowing you to monitor the engine and transmission's vitals. An Edge Juice With Attitude or Banks Six-Gun are Performance Modules that intercept and modify the outgoing signal between the ECM and the harness. Even though there are some differences in how they work, all Chips, Modules, and Programmers will improve your vehicle's performance. Hand Held Programmers such as SCT, Diablosport and Superchips plug into the OBDII port and reflash the ECM with proprietary tuning.
