4 Cylinder Deactivation and Engine Stop-Start Cancellation Device for GMC, Chevy, Cadillac

A 2-in-1 device that disables the 4 cylinder mode and cancels automatic engine stop-start. Forget about AC issues and the annoying Start-Stop system. The device connects to the vehicle's computer behind the front left wheel liner, as shown in the picture. Works with Cadillac, GMC, and Chevy 1500 models from 2021 to 2025. When the device is removed, factory settings are restored without leaving any trace.
