FAQ
Is Stage 1 safe for the engine?+
Yes, Stage 1 is a mild optimization within factory safety margins. We use dealer-level equipment and verify results on a dyno.
How long does it take?+
Usually 2–4 hours, including diagnostics, remapping, and a control measurement on our dynamometer.
Does it affect fuel consumption?+
Stage 1 can reduce consumption (better torque curve) or slightly increase it under aggressive driving. On average, consumption stays the same.
