Range Technology AFM/DFM Disabler Module

Has the Active or Dynamic Fuel Management system in your V6 or V8-powered GM car been slowing you down? Are you tired of the annoying shuddering of your engine and the drone it produces from constantly activating and deactivating cylinders? Meet Range Technology's answer: the AFM/DFM Disabler. Our module is plug-and-play, and reverts your vehicle back to stock when removed. Because no tuning is involved with your vehicle's computer, this product will not void the factory warranty. Not only does the AFM/DFM Disabler keep your vehicle running smoothly, it will have you running on all cylinders, all the time.

bought this for my 2014 Silverado 5.3 LT. No more hesitation, and its a good piece of mind to know that it will reduce the chance of lifter issues in the future. AFM seems like a good idea but its a flawed system. If you own a vehicle that can accept the module I would recommend anyone to get this. Honestly see no difference in the mpg's without the AFM. KEEP YOUR V-8 A V-8!!! A+

I just installed this on my 2017 z71 Silverado and now it runs like a dream, 100% recommend this!! well worth the money

Just added one to our 2020 Suburban. Saw an immediate difference in acceleration and power. My wife said it runs better than before. 100% satisfied!

This works soooo well. The suv drives soo nice no more shuddering that feels like the transmission is about to go out, no more drone noise I love itttt.

I got this for my 2010 Camaro. Big difference! No more shuddering, better throttle response and no more annoying AFM exhaust drone.. Plus I feel much better not having to worry about potential AFM lifter issues in the future. As far as gas millage I've had no negative impact.

Just got one for my 2014 Silverado 5.3. Works awesome. My truck has 162k miles and i regret not buying this sooner. What a fucking difference. No more hesitation or shitty V4 mode exhaust note.

Just installed this in my 18 Sierra. What a difference instantly. I was never happy with the way it drove with the afm, even thot about trading it in for a different vehicle but after plugging it in and driving it for a few minutes I immediately noticed the huge difference. Thanks Range for makeing this product for us V8 guys.

I have one installed on a 2015 Silverado for going on 2yrs.... Can't Beat It.

[joshuadavid]

I just ordered mine yesterday and I can't wait to get it delivered!

[PrestonOBrien]

I just installed in a 2023 Camaro LT1 (6.2) with A10 and it works perfectly.

[joshuaraffensperger]

Yup this will be going on my 2013 Suburban!

[dkhill]

Just installed this on my 2011 Yukon Denali. And I can feel the difference. No more hesitation instant power from my 6.2

[REVNUMANEWBERN]

There ya go, we need MORE companies to design plug and play setups that disables the factory NONSENSE ! Go Brandon !

[putz]

when will we see this for the '21 6.2 10 speeds? lots of people dont want the hassle (or cost) of the Pulsar LT option

If you own a GM 5.3 or 6.2 Buy this!!!! My 18 5.3l nothing but wired issues with the trans. Dealer trip after dealer trip. Got pissed off figured for 200 bucks maybe? Or trade this in... Momma I could tell in 5 mins. I was waiting for the dreaded odd ball shit to 3rd nope, then I was waiting for the intermittent clunk noise on down shift nope. Or the odd harmonic / shutter crap. Drove 1 hour in utter amazement it fixed the damn problem. Shifting normal all power its a v8 and stays a v8. And it woke up the motor. Unplugged it and put it my 14 with 6.2l to try with over 100k on it. Holy batman! It woke the motor up big time and ironically the transmission shifts better. Back to the 5.3l motor honestly I'm getting better fuel milage with this thing and the stupid miss that chevy dealer said is normal is gone. Thank you for provided a problem to all chevy owners and shame on gm for this disaster of an engine management system aka afm. I really like the fact it a simple as plug it it wait a few second for it to do it magic upon first plug in. then just start the truck and drive. Brilliant! And it won't void my warranty 😁 got to get a second one for the other truck. I'm just amazed and my wife drove it with it Un plugged and then plugged in and she it oblivious to car stuff and she even said the truck runs way soother shifts crisper and is just me or is it faster now when you push the gas pedal? Cause it I laughed she said I want one too

My cylinder 3 valve spring lifter just failed causing the push rod to get bent on my 2014 Sierra with 54, 000 miles. Luckily it didn't damage the piston but since the engine is apart I'm having all new lifters and guides installed.. very expensive at $5, 000. Going to order this guy in hopes to prevent this from happening again.

Does the range needs to be updated every time in a while?

[Brian.]

my engine blew on my 2011 escalade, starting with a lifter issue, i think it was because of AFM, i just bought a 2018 escalade with 40k miles on it, i think I'm going to get the disabler

[russellbabb]

What’s the diff between the red, green and blue versions?

Sorry for just not going to the website to do further research haha but maybe you could save me time and just give a quicker breakdown of them. I’m definitely looking into getting one, will it suit my 2021 GMC Sierra elevation 1500? Or out of the three options, which is best recommended ?

Thanks in advance!

[paulperalta]

Does this also remove the rev limiter?
