AFD Chevy Silverado / GMC Sierra 5.3L 2020+ ProFlex DXI Plug N Play Flex Fuel System

ProFlex DX Plug N Play flex fuel system for 2020+ Chevy Silverado / GMC Sierra 5.3L. This system allows you to start making more power and running cooler with E85. True plug and play flex-fuel kit for GM Vehicle in about an hour with no tuning required! Customers can expect 40-45WHP gains on E85. The ProFlex DXI product line is backed by a limited 12 month warranty. With over 2,000 miles of street, track and dyno testing this new technology has been carefully developed specifically for direct injection systems. It is the only real time flex fuel option available for your car on the market today.

Note: Installation of the ProFlex DXI is similar to our other plug and play systems, however there is a single pin connector that must be installed inline on an existing wire. If you are not experienced with crimping connector pins on wires, we strongly suggest professional installation.

*Notice: If you’re running an aftermarket supercharger that includes a tune (e.g., Whipple, Magnuson, Harrop), please note that these tunes typically maxout the factory DI system. We highly recommend you have a fuel system that can handle the increased fuel demands (e.g., larger DI injectors, higher flowing low/high-side fuel pumps, port injection etc.) and getting a specific E85 or flex-fuel custom tune.
