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 ## 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 | | Brand Name | Range Technology | | Customer Reviews | 4.4 4.4 out of 5 stars (208) | | Included Components | Main component only | | 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 - **Automotive Fit Type:** Vehicle Specific Fit - **Brand:** Range Technology - **Operating system:** All - **Power source:** Corded Electric - **UPC:** 650245073286 810505026708 860001618617 ## Images ![RA003R AFM/DFM Disabler-Red - Image 1](https://m.media-amazon.com/images/I/6111rQ5EM7L.jpg) ## Available Options This product comes in different **Color** options. ## 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.
