REAL EXPERIENCES FROM REAL DRIVERS
See what GM drivers are saying about Brivia™.
-
★★★★★
“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.”
-
★★★★★
“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.”
-
★★★★★
“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.”
