When to choose which fuel sensor do you need?

Standard GM/Continental Flex Fuel Sensor: Perfect for those making less than 700 crank horsepower these sensors are extremely reliable. 600LPH is the max flow we recommend.

*Flow picture shows loss of psi as flow is increased.

AFD Billet E-Sense Flex Fuel Sensor: High-flow sensor perfect for those making 700HP+ this sensor will also add fuel temperature monitoring using the ProFlex Connect App.

ProFlex Commander vs ProFlex Commander Pro?

Standard Commander: The go-to option for stock or mildly modified vehicles with factory fuel injectors and naturally aspirated setups. No tuning required—perfect for reliable, daily-driven performance builds. Not recommended for supercharged or turbocharged applications or setups using injectors larger than stock. Check out the Pro System features below!

Commander Pro: Designed for high-performance applications running power adders and upgraded fuel systems (e.g., 60 lb injectors or larger), this setup offers enhanced injector control for high-flow injectors. We recommend the Pro System for those who already have or is planning to add a supercharger, turbo, or larger-than-60 lb injectors in the future as this system grow with your build. We recommend getting an E85 or flex-fuel tune with this system, especially if you’re using a power adder that includes a tune (e.g., ProCharger, Whipple, Magnuson) or if you already have a custom tune installed.
