“The ProFlex Commander system is my number one choice for running E85. It’s plug-and-play with no tune required. Even for my currently non-boosted Mustang I’ve seen gains on the dyno. Easy install with great customer service as well. Would recommend 10/10 times!”

“The ProFlex Commander is a must have for any E92 M3 owner looking to get the most performance out of the car. Plug-and-play, no headaches with mixing fuel. Definitely wakes up the car! I am extremely happy with this purchase!”

“The ProFlex Commander has unleashed hidden power my Supercharged E92 M3 was keeping dormant! I would highly recommend the ProFlex Commander to any N/A or Boosted engine. I am extremely happy that my car has the ProFlex Commander from Advanced Fuel Dynamics for my E85 setup!”

“This mod was easily one of the best mods I have ever done. Dyno verified 40+WHP improvement on my ESS 625 at 50% E85 transformed my car into a beast. Easy plug and play installation, real time monitoring of E85 blends, and MORE POWER. It’s a no brainer to get this!!”
