AFM Disabler Active Fuel Management Compatible with Chevrolet Silverado 1500 V8 5.3L 2010-2018 Models and Trucks, SUVs with GM V6 V8 Engines,Gold

I absolutely hated when my truck felt sluggish when switching from V4 to V8 and this little device is just plug and play so very easy to install! It has worked flawlessly so far. I have only had it for a couple of weeks so far but very happy with this purchase and highly recommend! Truck isn't sluggish anymore, no unnecessary shifting which is hard on transmission etc. Say goodbye to all VVT problems with this device, you wont regret it and itll make your vehicle pays and components last much longer without any unnecessary wear and tear. Highly recommend

Ordered this for my dad's truck and came in very fast. Truck runs very smoothly and no issues with it yet. 2015 Silverado with 58430miles on it. Changes the oil and filter very often so hoping we don't have engine problems. Great part,seller, and fast shipping

Works Exactly as Described! I bought this AFM Disabler for my Silverado 1500 with the 5.3L V8, and it made a huge difference. The truck now stays in full V8 mode all the time, no more annoying switching between 4 and 8 cylinders. Throttle response feels smoother, and I noticed less vibration at highway speeds. Super easy to install—just plug it into the OBD port and you’re done. No codes, no issues, and it can be removed anytime. Definitely worth it if you want to protect your engine and enjoy a smoother drive. Highly recommend!

Much better shifting pattern and better gas mileage. Works great!

Plug and play AFM disabler that works just as advertised. It doesn't draw power when not in use and it started working as soon as I plugged it in and cranked my truck up.

Would not recommend. First 3 or 4 days truck had better response, fuel mileage and no rough idling. After 4th day as truck was idling, speedometer started bouncing, engine started miss firing. I immediately pulled AFM out of OBD port and truck went back to normal. I shut it off plugged AFM back in and started truck, same result after about 5 minutes. Don't try it.

Almost a year with it in my 2017 and it works perfectly still. No issues no complaints

Works good, but it runs the battery down if you leave it plugged in.

Has been working great in my 2018 GMC sierra 5.3L V8 It shifts better. Fuel economy is a little better... Went from 1L - 5km to 1L - 7km but that's just bonus. The truck no longer goes down into v6 mode and it runs A LOT smoother. No more shifting up and down for every hill on the highway. Set cruise and it just hums along at at 1300ish rpms the whole drive. Should save my truck from the known stuck lifter issues and wear on my transmission.

Funciono perfectamente ahora no cambia a V4

Installed it in my 2018 sierra 5.3 litre. I had some shuttering issues (probably torque converter related) and hard shifting and lazy acceleration also a bit of a rough idle. This little unit has made all of these issues disappear. Not sure how but my truck now works amazing and hopefully it keeps working well. Has not hurt gas mileage in fact it might be better but more time to really tell. Amazing unit for the price! Highly recommend

Muy bueno, cumple las expectativas

Lo utilicé y funcionó, solo que me alarmó el tablero y al escanear me arroja fallas en trasmision, no sé si sea normal
