Attached to 2017 GMC Sierra Denali big difference works great would recommend 👍🏾

It’s been reliable so far, though I do wish it came with a small storage case or better instructions.

Not perfect for everyone, but for me it solved one of my biggest frustrations with my truck.

Literally plug-and-play. No setup, no coding, nothing complicated. I like that it doesn’t mess with the ECU at all—just unplug it if needed. Been using it daily and it just works.

Price felt a little high at first, but compared to possible repair bills, I get it.

Makes highway driving feel less inconsistent.

Used it through some freezing mornings without issues. That was one of my biggest concerns.

Product feels durable, not cheap plastic. Connection was snug and worked right away.

Was skeptical at first, but I can actually feel the difference. My Silverado feels less hesitant.

Took longer to open the package than install it.

AFM is great for fuel economy, but not for driving feel. This fixes that without messing with the ECU or doing anything permanent.

Main reason was avoiding potential AFM problems later. Can’t speak long-term yet, but so far it’s been exactly what I wanted.

Tried a lower-priced version before and had issues. This one feels more solid and has been trouble-free so far.

Didn’t expect such a noticeable improvement from something this simple. Took me less than a minute to plug in, no tools needed. The throttle response is way more consistent now, especially in city driving. No lag, no weird shifting. Definitely worth it.

Did a road trip after installing—definitely a smoother ride.

City driving used to feel inconsistent. Now it’s smooth every time. That alone made it worth it.

I don't usually write reviews. I was very hesitant about getting this because it was so much cheaper than the other options. It works perfectly fine. It's plug and play. No issues at all. It stays in V8 the whole time and the is so much smoother.
I lost no mpg. If I did it was less than 0.5 mpg
I love it. Five stars for sure.

Awesome product! My idle immediately was better, no more hesitation, no dash lights, constant power going down the road. My motor is no longer confused. This disabler is not coming out of my OBD reader, it is a permanent fixture. I dont know for other people, but the disabler shuts off when not in use so as to not drain the battery.

Good price, fast shipping and nothing negative to report. After having it over a month and half engine performance and gas mileage has improved. Would buy again.

Bought for a friend and does the job!

SIMPLE TO USE, PLUGGED IT IN AND IT STARTED FUNCTIONING DISABLING AFM WITHING 5 SECONDS.

Works great!

I installed this product on my truck and the results are perfect! It immediately resolved the unstable idling and jerking issues caused by the original AFM system. The installation process was very simple, and the device feels robust and reliable. In short, highly recommended – definitely a five-star product!
