Mercedes ECU Tuning C43 C450 GLC43 E43

Gain up to 485 HP & 530 lb-ft of Torque — Unmatched M276 Tuning Power

Tired of weak throttle response, turbo lag, and factory ECU limitations on your V6-BiTurbo engine? Our M276 ECU tune delivers instant torque, faster spool, crisp gear changes, and a brutal midrange punch—all while maintaining full OEM reliability and drivability.

📈 Real-World M276 Performance Gains

  • Up to 485 horsepower and 530 lb-ft of torque with supporting mods (downpipes, intake, premium fuel).
  • Noticeably faster spool from the twin-turbo setup, especially in the midrange where these engines suffer stock.
  • Sharper throttle response and smoother shifts, turning sluggish factory behavior into aggressive, precise control.

💡 Why Choose Our Tuning?

  • OEM Reliability Preserved: Our M276 ECU tuning retains all factory safety protocols, so you get performance gains without sacrificing long-term reliability.
  • Daily Driver Friendly: Whether you’re commuting in a tuned E450 or taking weekend canyon runs in your C43, cold starts stay smooth, idle remains stable, drivability is refined, and fuel efficiency is improved—perfect for daily use
  • Tailored Experience: Choose your preferred fuel type (91–100 octane), customize burble aggression, dial in throttle response to match your driving style, and even choose max boost rpm range. This isn’t a generic map—it’s a refined performance experience built for your exact needs.
  • Undetectable at Dealerships – Our stealth-mode calibration is designed to bypass dealer scan tools and software updates. That means you can tune your AMG for power while keeping warranty peace of mind

🔧 Tuning Options

  • Handheld Tuner: Plug-and-play MyGenius programmer, 3 switchable maps included.
  • Bench Tune: Ship us your ECU for in-house calibration and fast return shipping.
