AFM Disabler Active Fuel Management Delete Disabler AFM/DFM Disabler Compatible with V6 & V8 GM Motors AFM Disabler 5.3 Silverado (Chevy GMC Sierra GMC Yukon Cadillac Escalade etc)4.3L 5.3L 6.0L 6.2L

Installation was very simple, and after connecting it, my engine runs perfectly, with absolutely no annoying AFM-related vibrations or shudders. I also appreciate its compact size and excellent workmanship; there were no unusual noises or electrical issues. My truck feels more powerful and reliable, especially under load. I highly recommend this product to anyone looking to improve engine performance and reliability—definitely a five-star product!

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.

Fantastic module for V6/V8 engines 🔥. Works with Silverado and Yukon perfectly. Easy to install, no tuning required, and immediately improves engine performance. Excellent quality and very reliable.

The results are fantastic! It feels like driving a brand new truck. Throttle response is significantly improved, and gear shifts are incredibly smooth. This plug-and-play device is perfect—easy to plug and unplug, doesn't overheat, and doesn't drain the battery. Finally, I didn't notice any change in fuel consumption. I highly recommend it; I tried two other devices before that didn't work, but this one truly works!

I purchased this AFM/DFM Disabler for my 2017 Chevrolet Silverado Black Widow with only 51k miles, and overall it has been a solid device. It has consistently kept my truck in V8 mode, which is exactly what I wanted. I had read some reviews mentioning concerns about the device draining the battery, but I personally have not experienced any battery issues while using it. It has worked reliably since I plugged it in. I also saw claims that it could improve fuel economy. In my case, I haven’t noticed any change from my 9.3 MPG average, but my main goal was maintaining V8 performance, and it does that well. The price was reasonable, and I would recommend this product to others looking to disable AFM/DFM. Note to seller: I’d also be willing to test and review more of your products in the future. 4-star review ⭐⭐⭐⭐☆

The results are exactly as advertised! Installation was incredibly simple, and it immediately improved my engine performance. Acceleration is smoother, and power delivery is more consistent. I'm very satisfied with its ease of use and the significant improvement.

Very happy with this. I have a 2015 Silverado LTZ with the 5.3 and have been having a lot of issues with the AFM. We all know with the AFM we are going to go through spark plugs and coils at a certain point. I started having transmission issues as well related to the AFM causing constant gear searching, serious lag, long shifts, etc. sometimes just feels like you're pulling a trailer. The transmission learns incorrect shift patterns dropping to 4cyl. So I had to replace a coil again and pretty tired of it at this point. Replaced the coil and also plugged this AFM disabler in. Fixed all my issues that I was having and driving so much better. I was reluctant to chose this being a mid range price point rather than the high dollar units. But this had good reviews and I am very happy with it. This isn't a permanent fix but will get me by until I do a proper AFM delete.

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!

Works great! easy install and no check engine codes are thrown while using.

worked perfect on my Camaro 2018

Just wonderful. No more rough downshifts and hesitation when I step on the accelerator. Much smoother drive. I got it for my 2020 sierra 1500 with the 6-gear transmission.
