LS Pros is proud to release a PnP flex fuel solution for 2003-2007 GM trucks. 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 applications benefit from the use of ethanol, and this kit allows you to switch between gasoline and ethanol without having to monitor your fuel content or adjust your fuel tables. This kit is 100% Plug And Play.
NOTE: Due to the nature of the 0411 (the PCM that comes factory with the GM Trucks) flex fuel logic is limited to 2 bar (up to 14 psi of boost). If you plan on running more boost than that, please purchase a P59 PCM as it will allow you to run up to 30 psi of boost.
