When we first installed the AFM/DFM Disabler & Auto Start/Stop Eliminator on our GM trucks, we immediately noticed a smoother driving experience. The frustration of constant engine shutdowns during stop-and-go traffic was finally gone, replaced by seamless idle operation. What stood out most was how easy it was to install-no complex wiring or technical expertise needed. We’ve tested it across various models from 2005 through 2024, and it’s consistently reliable for select 2025 models as well. This device has genuinely improved our daily commutes by reducing engine fatigue and conserving fuel, all while maintaining the factory look and feel. For anyone tired of the auto start/stop feature interfering with their driving comfort, this product is a game-changer. It’s a simple upgrade that delivers noticeable differences, making it a must-have for GM truck and SUV owners seeking a smoother, more efficient ride.
