  • ★★★★★

    “I spent 30 years in the trade, so I was skeptical. After running it on my 2018 Sierra for a month, I’ve had zero issues. The throttle feels more responsive, the AFM drone is gone, and I haven’t noticed any battery drain or warning lights. Definitely worth it.”

    Oliver G.

  • ★★★★★

    “After hearing about AFM issues, I asked my dealer what he’d do. He recommended an AFM disabler, so I gave it a shot. My truck feels smoother and pulls my trailer with plenty of power. I’m glad I installed it.”

    — Emmanuel L.

  • ★★★★★

    “My truck was feeling sluggish and the lifters were getting noisy. I decided to try the plug before spending thousands on repairs. The difference was noticeable right away — smoother driving and better throttle response.”

    — Kevin R.

KEEP YOUR ENGINE RUNNING CONSISTENTLY

AFM and DFM systems can automatically deactivate cylinders during certain driving conditions to improve fuel efficiency. Some drivers notice this as shuddering, hesitation, or changes in throttle response.

Brivia™ AFM/DFM Disabler is designed to prevent cylinder deactivation on compatible GM vehicles, helping maintain consistent V8 operation and a smoother driving experience.

Frequently Asked Questions

Will it fit my vehicle?

Brivia™ is designed for compatible GM vehicles equipped with AFM or DFM. Check your vehicle’s compatibility before ordering.

Will this void my warranty?

Brivia™ does not permanently modify or reflash your ECU. However, warranty coverage can vary, so check with your vehicle manufacturer or dealer for your specific situation.

Do I need tools or mechanical skills to install it?

No. Simply plug Brivia™ into your vehicle’s OBD-II port. No wiring, tools, or mechanical experience is required.

Will leaving it plugged in drain my battery?

Brivia™ is designed with low power consumption for normal use. As with any OBD-II accessory, avoid leaving it connected for extended periods when the vehicle is not being used.

Does this actually prevent expensive lifter failure?

Disabling AFM/DFM may reduce the cycling associated with cylinder deactivation, but Brivia™ cannot guarantee that it will prevent lifter or engine failure.

Will it throw a check engine light?

Brivia™ is designed to operate without triggering warning lights when used on compatible vehicles. If a warning light appears, remove the device and have the vehicle properly diagnosed.

Why is this cheaper than the $230 brand?

Brivia™ focuses on the core AFM/DFM disabling function without the added costs associated with higher-priced alternatives. Lower price doesn’t mean you have to pay for unnecessary extras.
