AFM/DFM Disabler Active Fuel Management Disable Device Compatible with V6 & V8 Gm Motors New Technology RA003

I’m half and half on this one. Sometimes it made my afm stop working like it’s supposed too and other times I couldn’t honestly tell. But it was very useful until I got my Tahoe tuned

Works as it should no need to spend the extra money on more expensive brands

Works as advertisec

Just plug and play

My Chevy was burning lots of oil and fouling plugs like crazy, and those aren't cheap. The problem is the afm sprays oil on the bottom of the pistons when it releases back from v4 mode to V8 mode. I have been driving in third gear for the last few years to avoid it ever going into v4 mode, but not all of the drivers in my home remember to do that...after suddenly burning through 4 quarts of oil in two weeks (and fortunately checking and topping off the oil and avoiding catastrophic engine failure) I bought this. We drive the Chevy at least once a week, and this does not drain the battery in that time, and it prevents the truck from going into v4 mode, so I am back to using a quart every couple of months or so instead of every trip to town. This will save me money at this rate, and I am also getting better mileage than driving in third was getting me.

The product didn’t do as expected and unfortunately my pickup kept setting off the check engine light and had to take it in to the shop 3 different times.🤦‍♂️

Initial post…Heard a bunch of people buying a disabler but couldn’t see myself spending $200+ for the Range AFM disabler, I ended up purchasing this one. Does the same thing, but if you want to buy the name brand then be my guest. This works just fine. No issues. Just plug it in and enjoy that V8 instead of V4.UPDATE February 5, 2024…After testing it out for a couple of days, I began noticing my V8 going to V4. I thought it was maybe a glitch or something but it continued to do that. So, I requested a refund and I ended up getting the Range which I did not want to spend money on. I guess sometimes you get what you pay for. Great customer service though and return was free through UPS label and refund was received same day.

I installed this AFM disabler on my 2016 Corvette (A8) and so far (only had it for a couple weeks now) it keeps the car in V8 mode all the time. I've not checked the gas mileage, but then who buys a Corvette for the gas mileage. Also, it's very easy and quick to plug in and unplug.
