93 octane vs E85 on a BMW E46 M3

“I used to tune cars for E85 for a living, but my tunes were always off in the real world because E85 at the pump is never a consistent percentage of ethanol. That’s when I invented the PROFLEX Commander. E85 tunes are insufficient and now obsolete. This is the best way you can run E85 and always make maximum power safely.”

-Ryan, Founder

Why Run Ethanol?

bg bg

The Ultimate Performance Fuel

Ethanol is the highest-performing fuel available, and it’s available at the pump! Ethanol is commonly referred to as E85, which is typically the highest blend at the pump, and not only gives your vehicle more power but burns cleaner and cooler.

Go Harder, Faster, Longer, Cooler

Running ethanol with the PROFLEX Commander will increase your M3’s horsepower and torque as well as lower your engine temperatures, which is especially useful for track days and races.
