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.

Comfortable and high quality
Color: Brown
This brown leather office chair is a great balance of comfort, style, and functionality. The rich brown tone gives it a classic look that elevates my workspace.The leather feels super smooth and high quality. Very easy to put together. It feels sturdy and well-built, with adjustable height. Size is just right for most offices. I love this chair, definitely an excellent choice.

Not the most comfortable but nice chair.
Nice quality chair but it’s hard and uncomfortable. Hopefully I will wear it in.

Good quality, but hard
Color: Brown
The leather and metal seem to be of very good quality. My son bought this as his office/study chair. He is starting medical school and liked the professional look of this chair. He is 6’ tall and 200lb. There does not seem to be an issue with the chair rolling even with his weight. The chair is very ‘hard’ not that comfortable if you need to sit in it for long periods. Since my son needs to be staying awake to study, this will work for him as he won’t be able to get too comfortable and fall asleep.

Easy assembly and smooth movement
This chair has been a great addition to my home office. The assembly instructions are simple and easy to follow.
The height adjusts smoothly, and the chair is very comfortable. I sit at my desk for about 9 hours a day, and this chair makes it easy to stay seated and work for long hours without discomfort. The cushioning and back support are solid.
It spins well, and the wheels move smoothly. The build quality feels sturdy and reliable.
Overall, a great value and a solid choice for anyone with a desk job. Highly recommend.
