I have always noticed the auto start stop makes the trucks transmission feel weird even when not going from a stop. I love how this keeps that feature off and I don’t have to press the button everytime I get into the truck. I do have to almost learn how to drive the truck again because it just feels different and almost like it has more power which I know it doesn’t, just more consistent. I have been watching fuel economy and think it may have gone down just a bit intown driving. I have only driven a short longer trip but seemed to actually improve on highway driving. I do think it will stay roughly where it was or possibly get a little bit better fuel mileage once I get used to the way it shifts now. Definitely less of the weird shifting with the transmission, more consistent. It was very easy to plug into the obd port and easy to attach with Bluetooth. Time will tell if this makes a difference on the longevity of the truck. It is a 2021 Silverado with the 5.3 and 65,000 miles. Review: Works as Advertised - Works great with my 2023 Blazer. Plug and Play operation disabled auto stop/start and AFM with no issues. Haven’t seen many options for this vehicle other than reflashing computer memory which to me is an inconvenience when it comes to getting the emission test done on the vehicle. ## Features - Vehicle Compatibility: Carbyte works with a wide variety of GM vehicles, including the 2022-2024 SUVs and 2022-2025 trucks, as well as 10-speed transmission vehicles — see supported vehicles list below. - AFM/DFM Disabler: In Full-Time V8 Mode, Carbyte disables the AFM/DFM system and keeps the engine firing on all cylinders, all the time. - Start/Stop Disabler: Eliminate the annoying Start/Stop feature, keeping your engine running 100% of the time. - Plug-and-Play: Stand-alone functionality allows Carbyte to work by simply plugging in the device.
