If you want something that you plug in and basically forget about, this works like it's supposed to. However it's not perfect. It does turn off the auto stop and the DOD. When slowing down and coming to a stop, the transmission sometimes studders (best word i can describe it). If you don't mind a few extra seconds (without the Range device) put the transmission in L and select the highest gear available. This keeps the auto stop off and it stays in v8 all the time. The truck will drive normally. Review: Does what it says. - I almost never write reviews but this thing legit works. It never goes back into V4 mode. It stays in V8 and my car is a 2SS 1LE. 2022. So it pops even more cause it’s pure V8. Literally goes on for like 6 seconds straight after flooring it. It’s crazy how a simple plug in can change so much. That’s another thing, it was very very easy to install. You just plug it in. That’s it. No setting, no nothing to adjust ## Features - Leaves no trace. Unplug it to return to factory settings - Range AFM/DFM Disabler keeps you in full power 100% of the time. - Simply plug into your onboard OBD-II port and it instantly begins working to eliminate the AFM system. - The power and control you need in any situation. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B084X5V8RR | | Brand Name | Range Technology | | Customer Reviews | 4.5 4.5 out of 5 stars (2,214) | | Global Trade Identification Number | 00860001618600 | | Included Components | Main component only | | Item Weight | 0.12 Pounds | | Manufacturer | RANGE TECHNOLOGY | | Operating System | All | | Power Source | Corded Electric | | UPC | 860001618600 728505768859 | | Unit Count | 1 Count | ## Product Details - **Automotive Fit Type:** Vehicle Specific Fit - **Brand:** Range Technology - **Operating System:** All - **Power Source:** Corded Electric - **UPC:** 860001618600 728505768859 ## Images ![Range Technology RA003B AFM/DFM Disabler-Blue - Image 1](https://m.media-amazon.com/images/I/719IP1jb2FL.jpg) ## Questions & Answers **Q: willl this work for a 2012 chevrolet silverado lt 5.3? thanks** A: It looks like a 2012 did come with Active Fuel Management system.
