When it comes to pure power and refinement, few SUVs command attention like the Mercedes-Benz ML63 AMG. Under the hood sits the mighty 5.5L twin-turbo V8 M157 engine, a masterpiece of German engineering that delivers both brute force and everyday luxury.

At Revhigh, we recently had the pleasure of working on Andy’s ML63 — a vehicle that perfectly blends performance and practicality. But Andy wanted more: sharper throttle response, smoother gear shifts, and a little extra power underfoot — all without sacrificing drivability or longevity.

🔧 The Process: Downpipes, Dyno, and a Transmission Tune

To unlock the ML63’s true potential, we started with upgraded downpipes and moved into a custom dyno tune tailored specifically for Andy’s setup.But we didn’t stop there. The transmission got a comprehensive tune as well — improving shift points, clutch pressures, and torque delivery.

The result? A perfectly balanced AMG that feels alive again.

⚡ The Numbers That Matter

On the dyno, power climbed to an impressive 400kW at all four wheels. However, after taking into account the car’s age and Andy’s concerns for long-term reliability, we refined the tune to a safer, more balanced 350kW.

That’s still a +200Nm torque gain, giving the ML63 an instant punch off the line and effortless midrange pull — all while keeping reliability front of mind.

This tune isn’t just about peak numbers; it’s about precision, balance, and drivability.

🚘 Why the ML63 M157 Responds So Well to Tuning

The AMG M157 engine is famous in the tuning world for its robust design and massive headroom for power upgrades. With the right calibration, it delivers supercar-level performance from a family SUV.

The key lies in custom tuning — not generic flash files. Every engine has its own quirks, and a professional dyno session ensures perfect fueling, ignition timing, and boost control.

If you own an M157-powered AMG (E63, CLS63, ML63, GL63, etc.), a proper tune can completely transform how your car drives — without compromising reliability.

💬 The Takeaway

Andy’s ML63 now strikes the perfect balance — power, reliability, and refinement.At Revhigh, that’s what we specialize in: tuning that enhances performance and preserves what makes your vehicle special.
