Range Technology Plug & Play AFM/DFM Active Fuel Management Disabler for GM Vehicles RA003G (Green)

I had received the Range Technology AFM Delete on 25 April 2022 and I have driven 1000 KMS on my Silverado LTZ 2009 with it since then. I wanted to post a detailed review after using it for a good amount of time and distance, so here it is!!This is literally the elixir that I my car needed. Since I bought my car I had replaced the lifters twice (which I know is a very common issue with Silverados) due to the crapiest AFM technology of switching from V8 to V4 and back when needed, Chevorlet had put into its cars. It was after the first change of lifters I came across the Range AFM Delete module which had very good reviews on Amazon and on various online platforms. But I was kinda skeptical and trusted that once I changed the lifters the issue wouldn’t happen again. And then it happened for the second time and that was when I knew I had to get it cause I had already spent a lot replacing the lifters and the oil manifold.I received it, and it was just plug and play into the OBDII Port, LED on the device blinked and couple times and then became solid green. I drove for some distance and the odometer DID NOT from V8 to V4 which means the device worked.Also before having the device I had noticed that while driving on the highway on cruise control intermittently the engine tries to switch between V8 and V4 and you can feel a slight push and pull the engine does when it cannot figure out if it has to stay on V8 or V4. This COMPLETELY VANISHED since I installed the Range device. More so I noticed that my gas mileage has increased and I’m now getting atleast 50-70 kms more on a full tank than what I used to get earlier and the car’s driving and the throttle response has been better than ever!!I WOULD SUGGEST THIS TO EVERY SILVERADO OWNER CAUSE LITERALLY THIS IS THE JAIL BREAK FOR YOUR CAR TO UTILIZE ITS FULL CAPACITY AND GET THE MAX OUT OF YIUR CAR IN TERMS OF LONGEVITY, MILEAGE AND DRIVING!!

Bought this for my 2019 Chevy Silverado trail boss. I was nearing 100,000 and have replaced my lifters 2x and my camshaft once all under warranty. I have installed this device in hopes of eliminating future problems.Easy to install and this is an awesome device. I had my doubts with fuel efficiency, but I actually save money on gas!!!! I guess because it is more efficient staying in V8 mode rather than switching cylinders...suck it Joe Biden with your electric vehicles, I have a V8 truck and love it!!!

Works exactly as advertised

Easy install! My 2018 Yukon Denali is now 100% V-8. One does not buy a SUV or truck for gas mileage but rather for performance. Small difference in gas mileage, big difference in performance! Also need to consider the issue of AFM lifter failure due to AFM stuck lifters...very costly repair.

No engine grief. 8 cylinder ALL the tme. Little change in fuel economy.

Bought this for 15 yr old Suburban. With nearly 300,000 on the odometer, the change from V8 to V4 was very rough and caused a severe vibration in the truck. Now all that is gone and it never drove better. Plus, mpg didn't change.
