The Mercedes-Benz CLA45 AMG is already a performance-focused machine straight from factory, but with VAITRIX Stage 2 ECU tuning, it unlocks a whole new level of aggression, power, and real-world drivability.
This isn’t just a small improvement — it’s a full transformation of how the car delivers power across the entire rev range.
📊 STOCK vs STAGE 2 PERFORMANCE GAINS
Stock: 360 HP / 45.9 kgm
VAITRIX Stage 2: 440.6 HP / 64.1 kgm
⚠️ +80.6 HP increase
⚠️ +18.2 kgm torque gain
That’s a massive jump in output, especially in a turbocharged 2.0L platform where mid-range torque makes the biggest difference.
🚀 WHAT YOU’LL FEEL ON THE ROAD
Once tuned, the CLA45 AMG becomes noticeably more responsive and aggressive:
✔ Harder mid-range acceleration (3000–4500 rpm)
✔ Stronger turbo response and boost delivery
✔ Improved throttle sharpness
✔ Better high-rpm power retention
✔ More consistent pull across every gear
The biggest difference is how quickly the car builds and maintains power — especially during overtakes and hard acceleration.
⚙️ WHY VAITRIX STAGE 2 WORKS SO WELL
VAITRIX tuning focuses on real-world performance, not just peak dyno numbers.
Key tuning improvements include:
✔ Custom real-vehicle calibration (not generic files)
✔ Optimised boost control strategy
✔ Improved ignition timing mapping
✔ Enhanced fueling calibration
✔ Stronger mid-range torque delivery
✔ Better high-rpm stability
This results in a smoother, more usable powerband rather than a peaky or inconsistent tune.
💨 MID-RANGE POWER – THE GAME CHANGER
The biggest improvement comes between 3000–4500 rpm, where most daily driving and performance situations occur.
In this range, the Stage 2 tune delivers:
More immediate throttle response
Stronger continuous acceleration
Less lag and hesitation
A more “pushed forward” driving feel
This is where the CLA45 AMG feels the most alive.
🔥 HIGH-RPM PERFORMANCE
Unlike stock calibration, which tapers power at higher RPM, VAITRIX Stage 2 maintains stronger output above 5000 rpm.
This means:
✔ Longer pull to redline
✔ Less power drop-off
✔ Better top-end consistency
📩 FINAL WORD
If you're looking to wake up your CLA45 AMG and experience a true performance transformation, Stage 2 tuning is one of the most effective upgrades available.
More power. More torque. More response. More excitement.
