Picks up 21WHP!

Our stock BMW E46 M3 test car put out a baseline 270HP on pump gas. After plugging in our PROFLEX Commander and adding E85 the car made 291HP on 75% ethanol. The 21WHP gain is felt across the entire the entire rev range, making the car faster both low and high in the RPMs. The customer feels a notable difference when running E85 over gas with the PROFLEX Commander.
