Maximize the potential of your M274 2.0L Turbo with a precision ECU calibration built specifically for the M274’s factory catalytic converter restriction. Expect noticeably quicker spool, stronger mid-range torque, and smoother power delivery — all while keeping every OEM safety system fully active.

🏁 Why Our M274 Tunes Stand Out

• 10+ Years of Mercedes Performance Expertise — Built and tested on our own M274-powered race cars and street builds.
• Proven on Track & Street — Calibrations refined across daily drivers, track cars, and dedicated race applications.
• We Only Sell What We Run — Every map we offer is one we run and trust on our own vehicles.
• Factory Safety Systems Preserved — All OEM knock, thermal, and limp-mode protections remain fully active.

🔧 Tuning Options

• Handheld Programmer: Flash at home with our MyGenius device (includes 3 custom maps).
• Bench Tune: Send in your ECU; we’ll flash it and return it ready to plug in.
