Give Your HD Gas V8 A Tune That Matches The Fuel You Actually Run

The 6.6L gas V8 in a 2020 to 2023 Silverado or Sierra HD is built to work, which is why it deserves a tune that is built for work too. The Edge Evolution CTS4 is made for these trucks, with octane specific tunes that let you match the calibration to the fuel you plan to run. Edge says the tuning improves throttle response, so the truck feels more eager when you ask it to pull, merge, or pass. It also optimizes the shifting, which matters on a heavy truck that spends its life towing and hauling. The monitor puts a color touchscreen in the cab, so you can see supported engine and drivetrain data while the truck works. You can read and clear trouble codes without leaving the driver's seat, and Wi-Fi updates keep the device current. Because the CTS4 also works with Edge's accessory system, you can add sensors later as your needs change. For an HD gas owner who wants more from the truck and wants to see what it is doing, this is a capable all in one upgrade.

What The CTS4 Packs Into One Device For A 6.6L Gas Work Truck

The Edge 85803 is the Evolution CTS4 tuner and monitor for 2020-2023 Chevrolet Silverado and GMC Sierra 2500HD and 3500HD trucks with the 6.6L L8T gas V8. Edge describes it as delivering powerful tuning and advanced monitoring, with octane specific tunes, improved throttle response, and optimized shifting. The monitor is a color touchscreen with a speedometer, in cab monitoring, data logging with 5 volt inputs, video capability, and Wi-Fi updates. It can erase fault codes, and it is compatible with Edge's Expandable Accessory System. Software and an instruction manual are included, and pods and mounts are available for the monitor. Edge states the part is legal under the provisions of the EPA's Tampering Policy dated November 23, 2020, and that it is not legal for sale or use in California.
