Why Stage 1 for the 2.4 JTD 136hp

Our Stage 1 calibration is designed for a completely stock vehicle — no hardware changes required. In practice this delivers a safe and reversible improvement in drivability.

Typical gains on healthy examples are from around 136 HP to 170 HP and from 310 Nm to 380 Nm (indicative; varies by condition).

What we do

  • Throttle response and power delivery refinement with a focus on smoothness
  • Road testing and post-map parameter checks

Safety and Warranty

We follow a conservative approach, maintaining thermal and mechanical margins to protect longevity.

The process is fully reversible (factory file can be restored) and requires no physical modifications.
