When it comes to modern performance cars, few platforms respond to tuning as well as the Mercedes-Benz C63s. This Stage 2 C63s is a perfect example of how the right calibration and hardware can unlock huge performance gains without compromising drivability.
Baseline Dyno Results (Before Tune)
Before any modifications, we ran the vehicle on the dyno to establish accurate baseline figures:
• Torque: 648.7 Nm @ 124• Power: 311.6 kW @ 246
Strong numbers from the factory, but there was plenty of untapped potential left in the ECU and transmission calibration.
Stage 2 Results (After Tune)
After installing our downpipe package and completing a full custom dyno tune, the transformation was dramatic:
• Torque: 801.5 Nm @ 128• Power: 398.4 kW @ 206
Gain Summary
The improvements speak for themselves:
• +152.8 Nm of torque• +86.8 kW of power
These are gains you can feel immediately—harder acceleration, stronger mid-range pull, and significantly improved top-end performance.
What Was Done
This build proves that you don’t need extensive modifications to achieve serious results:
• Custom dyno ECU tune• Revhigh downpipe package• Gearbox (TCU) tuning for faster, firmer shifts• Deceleration crackle added for enhanced sound and character
No additional bolt-ons, no unnecessary parts—just precise tuning and proven hardware.
Why the Results Are So Impressive
The factory calibration on the C63s is conservative, especially in torque management and gearbox behavior. By recalibrating these systems properly, we’re able to safely extract more power while improving drivability and shift quality. The added downpipes also reduce exhaust backpressure, allowing the engine to breathe and respond more efficiently.
The End Result
The car now delivers:• Stronger, more linear power delivery• Massive torque gains across the rev range• Sharper gear changes• A more aggressive and engaging exhaust note
All while retaining daily drivability and reliability.
