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

We haven’t had it installed for too long yet, but so far it’s doing exactly what it’s supposed to. My husband had no issues installing it—it’s literally just like plugging in a code reader into the OBD2 port. You just leave it plugged in, and it gets to work right away.After spending over $2,500 on lifter repairs, we got this hoping to avoid that whole headache again. The drop cylinder design GM uses has been nothing but trouble, and this disabler seems like the best way to avoid more expensive damage down the road.Even just from driving now, the truck runs smoother and shifts better without switching to 4 cylinders. It honestly feels more solid and responsive already. We’re hopeful it holds up long term, but we’re impressed with the difference it’s made so far.Why did you pick this product vs others?:Because, it was priced reasonably and a friend recommended this one for me. Functionality:So far so good definitely serves its purpose.Weight:it’s light as a feather literally lolSound quality:there is no sound

My suburban runs great with this 'Tuner.' NO it is not a tuner yet by Turing OFF the 8-6-4 mode on my suburban it has run far better and I do not have the fear in the back of my mind that we will have engine oiling or lack there of issues. Plug and play. I did a 2000 mile road trip in my 2105 suburban with a 5.3 in Early July (Hot) with this plugged in I averaged just over 20 MPG. We drove 75MPH mostly on interstate. with some sleep in the car times with engine running. I think the mileage was slightly better than what we used to experience before we installed this. The smooth running was far superior to what we used to experience. EASY and terrific modification to our 2015 Suburban.

This has been working great on our 2015 GMC Yukon XL. You can immediately tell a difference as even the idle is smoother. The vehicle runs better, shifts smoother. We have not experienced and voltage drain on the battery and our vehicle can sit for several weeks without being used. Highly recommend having this is your vehicle.

This thing works with out any side effects, and I believe it helped with the lazy shifts. The transmission shifts at slightly higher rpm and are spaced out better. I only have 3000 miles on it but I can't tell any difference in gas milage, getting 17.1 to 17.3 driving to work every week.

Got a defective one, seller communications was great, sent me a replacement. Works perfect!

Works as describedHas Set no codes.installed for awhile now over 500miles

I was skeptical on anything that only cost $39, But it worked just like it said it turned off the V4 mode stays in V8 mode and no more clicking and clanging and banging when it was in the V4 mode

2016 GMC Yukon XL Denali - Plug it in and that is all there is to it. All 8 cylinders all the time. Personal preference :: I will say that the blue light is pretty bright, so I put a piece of electircal tape over it.
