AFD Mercedes E55 AMG 2003-2006 ProFlex Commander Plug N Play Flex Fuel System

ProFlex Commander Plug N Play flex fuel system for 2003-2006 Mercedes E55 AMG. This system allows you to start making more power and running cooler with E85. True plug and play flex-fuel kit for Mercedes Vehicle in about an hour with no tuning required!

Customers can expect gains of 30+WHP and 20+TQ when running the ProFlex Commander and E85 on the Mercedes E55 AMG. The ProFlex Commander product line is backed by a limited 12 month warranty.

Note: If you have 60LB or larger fuel injectors or have an aftermarket forced induction system we recommend upgrading to the ProFlex Commander Pro System which was specifically designed to improve injector function in forced induction applications! See the product options button or PN# PCP-E55AMG-1!

*Notice: If you are keeping the stock supercharger tune (e.g., no smaller pulley, different supercharger brand, and/or larger-than-stock injectors), no additional tuning is required. However, if you plan to make any of these changes, we highly recommend upgrading to the Commander Pro system and getting a dedicated E85 or Flex-Fuel tune. (We also recommend you make sure you have a proper fuel system setup for the increase fuel load.)

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.

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.
