ProFlex Commander for LS Swap (LSx)

The ProFlex Commander for 1997-2015 GM LS Engine Swap (LSx) is a plug-and-play performance E85 flex fuel system giving your vehicle the ability to run E85, gas, or any blend right out of the box without the need to tune or switch maps. Please ensure that your build has injectors and a fuel pump setup that are capable of flowing full E85 before you install the system and begin using E85 fuel.
