DSX Tuning Flex Fuel Kit for Gen4 GM Truck

The DSX Tuning flex fuel kit is the original plug and play solution to adding flex fuel on Gen IV/Gen V GM V8 vehicles. Use these kits to add the ability to run anywhere from straight gasoline to straight ethanol as well as reveal the true power potential of your setup. Forced induction scenarios especially benefit from the use of ethanol, and these allow you to seamlessly switch between gasoline and ethanol without having to monitor your fuel content or reflash your tune.

Please choose your ECM from the drop down menu. For reference, most Gen IV trucks use the E38. The 2006 Trailblazer SS uses the E40, while the 2007-2009 Trailblazer SS uses the E67.

This kit uses:
-Genuine GM Flex Fuel sensor
-Plumbing kit made of corrosion resistant materials to ease installation
-Plug and Play wiring harness made with OEM connectors and terminals crimped with OEM tooling
-DSX Tuning 3D printed fuel line disconnect

PLEASE NOTE: It is possible to install this kit without tuning, but you will not gain the ability to switch fuels until the functionality is activated in the ECM through HP Tuners or EFILive. DSX manufactured components are covered against defects in materials and workmanship for the life of the product.
