AFM/DFM Disabler Active Fuel Management AFM Disable Device Compatible with V6 & V8 GM Motors

This plug keeps my 2010 Silverado in V8 mode. Certain GMs have the feature that was supposed to save gas by turning 4 cylinders off. There are apparently a number of issues that pop up as the engine ages, such as lifter issues and oil consumption. Also, there was a bump I thought was a transmission or rear end problem in city traffic but seems to have been the truck switching from V4 to V8 abruptly. Works as advertised and has bright LEDs to let you know it’s on. There are way more expensive ones, but for around $85, this is the most economical choice to alleviate the issues that arise in older vehicles with a feature that might have been a good idea, initially, but apparently doesn’t age well.

Finally a reliable way to keep my truck from moving between V8 and V4. Saving my truck and me thousands of dollars in repairs. My mechanic turned me onto this little device and It was one of the better purchases I've made. Also, I only drive my truck once every week or two, I just leave it plugged in and I haven't had any problem with my battery draining. So massive thumbs up from me.

Instantly worked in my 2015 Chevy Silverado 1500 4x4 it gave my truck much more power, solved the rattling sounds I heard when switching from v4 to V8 etc

So far works as advertised

This works perfectly. Have had it about a year now and still no issues

This thing works very very well. Keeps the truck in V8 mode, helps with the erratic shifting when it use to go into AFM mode, cylinder shut down. Truck rides very smooth, instant power and no more lag when driving. I highly recommend this to anyone that wants to get rid of the Active Fuel Management cylinder shut BS and wants to drive a smooth riding Chevy truck.

But this you can really tell the difference in your motor

The V4 function in my truck was driving be bonkers. It would studder a lot when accelerating and the constant switching back and forth between V4 & V8 was making me crazy.I noticed an immediate difference when I plugged this into my 2014 Silverado 5.3L. There's this road in town I travel on and usually my truck would shift hard as I accelerated to 40mph. I tried it again with the AFM delete and now the shifting is a lot smoother and it stays in V8. The overall acceleration feels way better now.I'm not sure if I feel a difference in pedal response, so in the future ill probably get a cold air intake and possibly a pedal monster/commander.
