## Description

The Range Technology AFM Disabler Device modules allow your vehicle to run in full cylinder mode at all times, preventing the Active Fuel Management (AFM) system from dropping cylinders. This patented technology is the only product that will disable AFM without reprogramming the factory ECU. You get full power delivery all the time without factory warranty concerns.

Review: My truck is a 2017 gmc sierra 1500 with a 6.2motor, 8 speed trans. It has been a night and difference for the better. Better fuel mileage, smoother shifts, more power at any given moment. My truck is a beast let out of its cage, or the perfect work horse pulling away. I have had this in my truck for three months. No shaking or hesitant shifts, just a very happy truck. Worth every penny. Just buy and thank me later.
Review: 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

*by M***K on 9 August 2024*

easy install,instantly sounded different, better performance all across the board,truck shifts better, gas mileage on day to day driving was a tad bit better,on a highway trip towing an atv trailer my gas mileage wasnt as good but a decent trade off for better power on the hills, will i keep it installed? most definatley!
