Review: 2016 Yukon 5.3 so far so great - Have had this in my 2016 Yukon with the 5.3 motor and 6 speed transmission for a month now. Works very well. Vehicle stays in V8 all the time with no other ill effects. I drive a lot of straight lines at 38 - 40mph which is when I would occasionally get the GMC shudder if I was slowing and speeding up often, but this completely eliminated it. I've not noticed any major change in fuel economy at this point, last I looked the average was down 0.1mpg if any. Would recommend this for sure! Easy to start using. Plugged it in to the port under the steering wheel, the lights flashed for 5 seconds or less, then good to go. Started the car and went for a drive, immediately worked. I considered the cheaper options here for $100 or so but decided it was worth another $100 to get the Range brand name and not goof with anything in my car. Just an update after 30 days of use: Still working very well, but I am noticing more of a full 1mpg fuel economy loss. Most of my day to day driving is around town, runs under 5 miles. I live 3 miles from work, so that definitely does not help, and dollars and cents wise is a very small impact, but wanted to update a larger economy loss than originally posted. Review: 10 month review and MA state inspections PASS - I have been extremely impressed with this Range AFM disabler since I first used it in May 2025. Besides the obvious fact that you will use more gas staying in V8 mode. It offsets the mild shudder without it and the brief hesitation when cruising at 75 and open it up. I didn’t notice any battery drain while I left it plugged in. (Always start vehicle with Range plugged into OBD and turned off while still plugged in) Lastly, here in MA we have to have yearly inspections and I unplugged Range minutes before the machine was connected to my OBD. Range has no affect on your MA state inspections. No red flags, no issues at all Absolutely love the Range AFM disabler ## Features - -Compatible with select Buick, Cadillac, Chevrolet, GMC, Isuzu, SAAB, Pontiac, Saturn & Suzuki GM vehicles - -Keeps you in full power 100% of the time, no more shuddering or dropping cylinders - -Fast and easy setup; simply plug into your onboard OBD-II port and it instantly begins working to eliminate the AFM system - -Does not reprogram your factory ECU, unplug it to return to factory settings - -Red LED version ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08941LBBR | | Best Sellers Rank | #34,981 in Automotive ( See Top 100 in Automotive ) #16 in Automotive Replacement Engine Management Systems #60 in Automotive Replacement Electrical System Relays | | Brand Name | Range Technology | | Customer Reviews | 4.5 4.5 out of 5 stars (1,051) | | Item Weight | 0.02 Pounds | | Manufacturer | Range Technology | | Operating System | All | | Power Source | Corded Electric | | UPC | 650245073286 810505026708 860001618617 | | Unit Count | 1 Count | ## Product Details - **Brand:** Range Technology - **Manufacturer:** Range Technology - **Operating System:** All - **Power Source:** Corded Electric - **UPC:** 650245073286 810505026708 860001618617 ## Images ![Range Technology RA003R Plug & Play AFM/DFM Active Fuel Management Disabler (Package may vary) - Image 1](https://m.media-amazon.com/images/I/6111rQ5EM7L.jpg) ## Questions & Answers **Q: Will this fit a 2021 trail boss?** A: At the moment our application guide only shows it working with vehicles up to 2020.

I own a 2010 Chevorlet Avalanche LT. I never knew nothing about this technology. My retired Coworker told me about it actually at a funeral. I ordered it. I called him and gave him the biggest thanks. The range is litterally saving my engine from ruin. Every time the Avtive Fuel management system kicks in I hear the lifters and pistons knocking and rocking. Thats a scary sound to me because that engine is under load doing that. The range device stopped all of that. My old V8 vortex engine is a happy girl now. Im loving the full time power especially when im climbing up 280 westbound here in New Jersey. We got some serious hills here and they are murder on transmissions and engines. I dont even care about the fuel mileage because I do drive local and local driving tears your car up anyway on the feul side. My truck runs so smooth now I dont have to play with the gas pedal anymore fearing that im damaging the engine. Now I drive with more confidence. Going up hills is smoother and I can actually keep up with traffic. The Avalanche was never speed pourpose built but now she moves. I took it other highway for a 40 minute drive yesterday to go somewhere usually I be in the right lane letting everyone go past me at speed but now I keep up with traffic. Its definately worth the money. All you do is litterally plug it in let it work its magic for a couple of litteral seconds and drive. It does not have any negative impact to your vehicle at all. Im so happy now. ## Frequently Bought Together - Range Technology RA003R Plug & Play AFM/DFM Active Fuel Management Disabler (Package may vary) - bbfly-A9 OBD II OBD2 16 Pin Splitter Extension 1x Male and 2X Female Extension Cable Adapter (2FT/60CM) - Range Technology RA003B AFM/DFM Disabler-Blue --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ph/products/321703863-range-technology-ra003r-plug-and-play-afm-dfm-active-fuel](https://www.desertcart.ph/products/321703863-range-technology-ra003r-plug-and-play-afm-dfm-active-fuel) --- *Product available on Desertcart Philippines* *Store origin: PH* *Last updated: 2026-04-23*
