Built in the USA from OEM-grade components and covered by a lifetime warranty from Dezine Group, the unit is compact, simple to install, and designed specifically for select GM 2007–2020 V8 models. It does not alter factory settings or require permanent modifications.\u003c\/p\u003e\n\n\u003ch3\u003eHow will this disabler affect driving smoothness?\u003c\/h3\u003e\n\u003cp\u003eWhen installed, the module prevents the engine from switching into V4 mode, which removes the sudden torque dip and vibration typically associated with AFM\/DFM transitions.
