Works easily
It plugs in easily but I read it will drain the battery if the truck sits too long so I have to take it out too often.

Suburban drives a lot better now.
So far so good. It functions as described. Side benefit is that shifting has improved greatly. I'm not sure why that is. Prior to using this my transmission would clunk in the gear or hesitate shifting. I assume that was the computer trying to decide whether to use V4 or V8 mode. My suburban drives so much better now. There may be a fuel economy hit but I'm sure it will be minor. It would probably matter more if you drive mostly on the highway.

Works great to stay in V8!
If you are having AFM/DFM issues like we have all had in our GM vehicles, this is the device you want. How it compares to other manufactures of similar devices, I cannot comment on. However, Holley Performance, who I believe is the parent company who manufactures these devices, is the best name in the business when it comes to anything and everything tuning related.This device is beyond easy to use as you simply plug it in, and forget it. Instead of the jerky shifting between V8 and V4 cylinder modes in my 2015 Silverado, it keeps my truck in V8 mode all the time. Gas mileage may be slightly worse, you're driving a V8 pickup, but who cares. Not having to (hopefully) not rebuild the top end of my engine when the lifters collapse again will pay this little gadget off 10X over again. I would highly recommend this to all GM truck owners with the 5.3 to delete V4 mode.

Works for 2019 silverado
Works perfect in my 2019 silverado, hasn’t killed the battery yet and it’s definitely sat for a few days in a row. Also I’m not sure why but I’m averaging a little better mpg which really doesn’t make sense. I do very little to zero highway so maybe that’s why

You need this
Works as described. Makes it drive like a different car. Whoever designed the AFM should be banished from society.

Will not work on 2020 silverado 1500 4.3 v6 engine
After reviewing their website for Range, it said their disablers will work for both V6/V8 engines. However, after purchasing and not noticing much difference I asked their customer service if it was compatible, it is not.
