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.
