Mercedes C63 AMG

31 Foot-Pounds of Torque

The team at Eurocharged ATX had already made a number of modifications to this 2012 Mercedes C63 AMG to increase the performance, but they installed a PROFLEX Commander™ so they could take the vehicle's performance to the next level by running E85.


The C63 AMG put out an additional 30 horsepower and 31 foot-pounds of torque running on 70% ethanol. The red line on the dyno graph to the right shows the vehicle's baseline run with pump gas. The blue line shows the gains made by adding pump E85 fuel to get to a 70% ethanol mixture. The brown line shows the additional gains the team at Eurocharged ATX were able to get by simply changing the tune with the vehicle still running 70% ethanol.

The vehicle owner and the team at Eurocharged ATX were all very happy with the results and plan to install headers and re-dyno the car to measure the additional performance gains.


All dyno tests were repeated a minimum of 3 times to ensure accuracy.
