"My 07 Tahoe was getting around 14 mpg and using 2 quarts of oil between the oil changes. When I decided to install this device, I changed the oil so I could better keep track of the oil consumption. After installing it, I haven't had to add any oil during the past oil change. Also, my fuel mileage went to around 16-17 mpg.” - Angelo D.

Why Buy Our AFM Disabler Device?

✅EASY TO INSTALL: This AFM Disabler allows your vehicle to operate in full mode every time you drive by ensuring that there is no drop in cylinders. It keeps your GM vehicle in V6 or V8 mode and prevents it from making a switch over to the 4-cylinder mode. Just plug it into your OBD-II port, four lights will flash in sequence, and only one light will be on when it is stable. It will instantly begin disabling the AFM system. After installation, you’ll get full power for your vehicle, with a visibly increased throttle response.

✅EFFICIENT: The disabler device will not reprogram the factory ECU so that the car is always in full-cylinder mode. It also ensures an uninterrupted and sufficient supply of power at every point in time and lowers the rate at which those expensive components of the AFM wear off. Suitable for all V6 and V8 GM vehicles, including cars, trucks, and SUVs.
