Mercedes M272 ECU Tuning – Precision. Performance. Personalization.

Gain up to +32 HP and +27 lb-ft with a tune tailored specifically to your Mercedes-Benz M272 3.0L / 3.5L V6.

Optimized for street, track, backroads, and highway — developed and proven on our own E350 for thousands of real-world miles.

🔥 Why Tune the M272?

The M272 V6 is smooth and reliable, but factory software keeps it restrained. Our bespoke calibration modernizes the platform, unlocking performance while tailoring drivability to your preferences — sharper response when you want it, refinement when you don’t.


📈 What You Can Expect

Typical gains: Up to +32 HP / +27 lb-ft (fuel and mods dependent).

  • Tailored throttle response — calibrated to your driving style, from refined daily comfort to sharp, sport-focused precision.
  • Fuel type flexibility — We can tune for 91 / 93 / 100 octane gas.
  • Optional burbles — off, subtle, or more pronounced to taste.
  • Refined daily drivability with immediate midrange punch on demand.
  • Expert calibration — built in-house, validated on road and highway, not just a dyno pull.

📷 Real-World Proof (see media above)

  • 34.5 MPG highway cruise on our tuned E350 — efficiency and performance can coexist.
  • 160 mph indicated in testing — stable, reliable top-end with headroom.

🚚 How It Works

Service Only (Ship ECU to Us) – $750
The purist’s option. Ship your ECU; we bench-flash and return it with your chosen settings: custom throttle, optional burbles, and up to 3 fuel maps (91/93/100). Ideal for owners who want the simplest, most direct path to proven gains.

Service + MyGenius Handheld Programmer – $1,050
Same bespoke calibration — delivered remotely. Read your stock file, receive up to 3 maps (91/93/100), and flash at home. Includes custom throttle and optional burbles.

💬 What Drivers Say

“This isn’t a generic tune. It feels like they built it for me — responsive when I want, smooth when I don’t.”
“Never thought my E350 could feel this strong. Worth every penny.”

For discerning Mercedes owners who value refinement as much as performance — this is tuning as craftsmanship, not commodity.
