Description

The DSX Tuning flex fuel kit offers a plug-and-play solution to integrate flex fuel capability into your GM vehicle. This system enables you to seamlessly run any blend of gasoline and ethanol, from pure gasoline to pure ethanol, thereby unlocking your vehicle's full performance potential, especially in forced induction scenarios. It boasts 100% clip-together plumbing, eliminating the need for wrenches. The components included are a genuine GM Flex Fuel sensor, a durable plumbing kit constructed from corrosion-resistant materials for reliable performance, and a plug-and-play wiring harness utilizing OEM connectors and terminals crimped with OEM tooling. A DSX Tuning 3D-printed fuel line disconnect tool is also provided. While the kit can be installed without immediate tuning, its flex fuel switching functionality will only become active in the Engine Control Module (ECM) after being enabled through software such as HP Tuners or EFILive. DSX manufactured components are covered by a lifetime warranty against defects in materials and workmanship, while the GM sensors carry a 90-day warranty. This product is proudly MADE IN AMERICA.
