    • ProFlex Commander 2017 Ford Mustang GT Coyote results with E85 - +13 whp

      The ProFlex Commander is essentially a flex-fuel sensor that helps the ECU adjust to E85 fuel. Depending on the motor this results in power gains thanks to the additional octane. It's essentially cheap race gas as most of you already know.


      Is it worth the cost? Absolutely. Even on a port injected 2017 Mustang GT Coyote motor the car picks up 13 horsepower at the wheels with gains throughout the entire curve:


      This 2017 Ford Mustang 5.0 was completely stock until we added our plug-and-play PROFLEX Commander. After plugging it in no tuning required we saw big gains across the whole rev range, as much as 20 extra WHP on E85 between 4500rpm and 6500rpm. Peak power baseline at 6700rpm on pump 93 was 380 and the peak power was 393 running E85 at the same rpm.
      For a plug and play E85 solution this is a hard product to beat.

      Unfortunately, it only works for the earlier Coyote motors and not the updated 2018 version with a dual-injection fuel system. Hopefully they will address the new Coyote soon.
