DYNO PROOF: Untuned Power! The ProFlex Commander Delivers BIG E85 Gains on a Tuned BMW (No Retune Needed)

Easiest Power Ever? We Put the ProFlex Commander to the Test

Making more horsepower should be simple. If you've ever felt intimidated by the complexity of tuning software, special tools, or endless hours of calibration, this video is for you.

In our latest feature, "Flex Fuel Install So Easy, My Camera Guy Can Do It | BMW 128i Flex Fuel Install," we follow our camera operator, Ethan, as he installs the Advanced Fuel Dynamics ProFlex Commander on his BMW 128i. The goal was to prove how easy it is to unlock the performance of E85.

The result? Not only did Ethan complete the installation with zero prior experience—proving it’s a truly plug-and-play solution—but the dyno results shocked us all. The ProFlex Commander delivered significant power gains with E85, all while using the car's existing 93-octane pump gas tune.

The ProFlex Commander Advantage: Power Without the Tune

The most groundbreaking takeaway from this dyno session is the ProFlex Commander's ability to maximize power without the need for an expensive or time-consuming retune.

Most bolt-on power adders require a custom tune to run safely and effectively. The ProFlex Commander is different: it acts as a complementary mod, automatically adjusting for the higher octane of E85 to safely increase performance, regardless of your vehicle's current state.

Key Performance & Compatibility Highlights:

  • Significant, Unexpected Dyno Gains: Simply adding the ProFlex Commander and E85 fuel resulted in power increases that exceeded our expectations, demonstrating the immediate performance benefit.
  • Zero Tuning Required: The system makes safe power by automatically adjusting fuel delivery for any ethanol blend, meaning no special tools or training are necessary for installation or operation.
  • Seamless Integration with Existing Tunes: The car was previously tuned for 93 octane, and the ProFlex Commander worked flawlessly, causing no issues or conflicts with the existing calibration.
  • Complements All Modifications: Whether your vehicle is bone stock or heavily modified with a custom tune, the ProFlex Commander is designed to enhance and leverage all other performance parts already installed.
  • The Next Plug-and-Play Mod: The ProFlex Commander is rapidly becoming recognized as the essential "next step" bolt-on for enthusiasts looking for substantial, safe, and easy power.

Why the ProFlex Commander is the Next Essential Mod

The ProFlex Commander empowers you to maximize your vehicle's performance on E85. It’s a true plug-and-play mod that offers the flexibility of running pump gas or E85 without ever having to touch tuning software.
