For long-term storage, unplugging the device is recommended to avoid any small parasitic draw over months of disuse.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eUltra-low standby current to preserve battery health\u003c\/li\u003e\n  \u003cli\u003eEngineered to reduce AFM\/DFM-related valvetrain variability\u003c\/li\u003e\n  \u003cli\u003eDurable housing and electronics for long-term plug-and-play use\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eWho is this for? Drivers who own GM trucks or SUVs with factory AFM\/DFM and want a reversible, non-invasive way to stop cylinder deactivation for smoother and more predictable V6\/V8 performance. It’s aimed at commuters, tow vehicle owners, and enthusiasts who prefer consistent throttle response without modifying the ECU. Confirm your vehicle’s AFM\/DFM system and compatibility before buying; this device is not a tune and is not intended for vehicles without supported systems.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Will this device permanently change my vehicle?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: No. It’s a reversible OBD-II plug; unplugging returns the vehicle to factory settings with no ECU changes.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Does it work on all GM engines?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: It works on GM V6\/V8 engines with factory AFM\/DFM (4.3–6.2L).
