This ST-3 came in for a proper custom calibration and left with a solid, proven gain.

240HP standard
282HP after tuning
Tested and confirmed on the dyno

No guesses
No generic file
No “should be about this” figures

Every change was data logged, tested and refined on the car itself. That is how you get real, usable power and keep everything within safe limits.

Airflow checked
Fueling monitored
Boost control dialed in
Ignition mapped correctly

You cannot safely increase power without knowing what the engine is actually doing. That only comes from proper testing and data logging.

The result is a car that feels completely different to drive. Stronger through the range, smoother delivery and performance you can actually rely on.

We do not flash and hope.
We test, develop and prove.

Multiple rolling roads
Advanced diagnostics and data logging
Injector testing petrol and diesel
Carbon cleaning and walnut blasting
Factory level diagnostic systems
