M113K ECU Tune

The M113K supercharged V8 is one of AMG’s most durable and iconic engines. From the factory, however, the ECU calibration is conservative, prioritizing smoothness and long-term reliability over performance.

The DTK M113K ECU Tune safely unlocks the engine’s true potential by optimizing supercharger control, ignition timing, fueling, and torque management — delivering stronger, more consistent power while maintaining OEM drivability.

Every car is tuned from scratch based on its exact configuration. No off-the-shelf files are ever used.

What the ECU Tune Does

• Optimized supercharger boost control

• Refined ignition timing for increased torque

• Calibrated fueling under load

• Sharper throttle response

• Smoother and more linear power delivery

• Removal of factory speed limiter (where applicable)

The result is an engine that feels stronger everywhere, not just at wide-open throttle.

Power Gains

Typical gains on a stock vehicle:

• ~+40 wheel horsepower

With smaller supercharger pulleys, upgraded cooling, and supporting hardware, gains increase substantially.

⸻

Drivability & Reliability

Despite the power increase, drivability remains factory-like:

• Smooth cold starts

• Predictable part-throttle behavior

• No harsh transitions

• Safe operating limits for stock internals

This makes the tune ideal for both daily-driven and performance-focused M113K builds.
