AFM Disabler ECULOCK Active Fuel Management Disabler AFM/DFM Disabler Compatible GM Tracks & SUVs 5.3 Silverado Sierra Tahoe Yukon DOD Delete

Bought this for my 2016 Silverado w/5.3L. And I am so pissed, that I did not purchase this years ago. It almost feels like it added HP. But mainly my Chevy is running better than ever. I do not notice a GPM difference and even if there was I would still highly recommend. Great price for a great product

AFM/DFM works as described. It keeps the engine in 8 cylinder mode. Does not seem to affect anything else but I have only used it a couple days so won't know for sure until I use it longer. Seems to be well built. Only con is there are no instructions to know what the three lights mean when they sequence. Does not seem to drain battery when left plugged in.

Plug and play, works great so far. Shuts off AFM on our 2008 GMC 1500. Hope it stands the test of time.. Many products do not these days.

Works as advertised no battery drain issues truck runs better with it

Works great

Works as it should, I couldn’t tell a huge difference in driving down the highway but when I am hooked up to my boat (main purpose in buying) it’s a huge difference. Still to early for a 5 star review only have had for a few days

This product works on my trucks that have afm. 2018 Colorado and an 08 avalanche. Does what it is supposed to.

Works as stated. Easy to install. Great value for the money. Glad I took a chance on this product.
