NEW RANGE TECHNOLOGY AFM-DFM DISABLER,RED,COMPATIBLE WITH V6 & V8 GM MOTORS

Great Device, does what it’s supposed to do and no engine check light, gas mileage is the same with or without

Does what they say it'll do. Keepsy truck running on 8 cylinders full time.

Does what u want it to do

I have done multiple DOD deletes and if you cannot afford to do one immediately then I recommend buying this! (IT WILL NOT FIX DAMAGE ALREADY DONE!) it will help prevent what will eventually happen down the line. So if you haven’t gotten it yet, get it! Do not buy a different brand they’ll cause electrical issues and other goofy stuff, spend the money on this one. Super easy to install, plug and play no messing around. It’s super cheap insurance to have. Doesn’t “tune” or “add power” just locks in the AFM to v8 mode or v6 mode (depending on application)so it’s not shutting off cylinders. It’s a great cheap product to hold off the inevitable a little longer.

I am a professional technician. I have heard all of the horror stories of how the AFM systems on GM 5.3 engines have a high failure rate with the valve train and cam. I don’t want it happening to me. I put the Range on my 2019 Suburban and so far so good. The OnStar still works fine and allows me to control things on my phone as before. It reports all service reminders tire pressure and fuel level as before. Some people said they lost that. Upon further use, I see that there are some diagnostics it fails to report if device is in use. They are emissions, engine trans, abs,airbag,stabiltrac. All you have to do is unplug and go for a 5 min ride and all of this resets. If anything wrong, then have a dealer look at it. I'm not worried about it. I think it will save the cam and lifters in the long run from constantly turning back and forth from 4 cyl to 8 cyl. Best of all it stays in V8 Mode all the time and the lifters cycling all the time stops and should make the engine last a lot longer.

At this time unit is doing as described reason for no 5 star I've only had it a couple days and the price is a little expensive.

I plugged it in and noticed the difference immediately. Truck shifts better, and I don't get that burping sound from the engine. More power and smoother. Gas mileage went down maybe about 1 mile per gallon. Thoroughly satisfied.

Works exactly as advertised.

Great

I love the afm delete, I have been running it on my 2016 Sierra 5.3 6 speed for the last 3000km and never had a hitch so far with engine lights or codes... Etc. It disables v4 mode all together and let's you're V8 stay a V8. Another thing I like is no light stays on when the vehicle is turned off only when it's running and it's hardly noticeable. Also I find the truck shifts better between gears no more drone from the v4

Not a problem with this item. Works very well

I wish I had seen this item before. My 2015 Sierra has always shifted poorly, shuddering and lagging as well as banging hard into 2nd. Shifting between 4 and 8 cylinders was starting to become more noticeable. The truck does have 220000k on it, so some wear and tear is expected. After adding this module shifting became smoother and more responsive with little change in mileage. So happy with the outcome.

Works exactly as advertised, truck is smoother and more quiet.👍👍.
