*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.
