Multiple logged runs confirmed consistent and repeatable results.
DEIZ performs all tuning calibrations on its in-house dynamometer to ensure accuracy and reliability. The dyno allows precise measurement of horsepower, torque, boost, AFR, and temperature behavior, enabling fine-tuning for both performance and safety.
DEIZ also hosts Dyno Day events, open to the public, where drivers can test their vehicles and review live data.
Chip tuning modifies the ECU to enhance engine performance:
- Stage 1
- Stage 2
This results in a more responsive vehicle suitable for demanding driving conditions.
