Holden Trax — Engine Variants & Typical Gains
Every Holden Trax file is developed from the vehicle's own stock read and your declared hardware, then refined against your data logs using HP Tuners.

|---|---|---|
| 1.4L 16v 140hp | 139 → 170 hp | 200 → 260 Nm |
| 1.8L 16v 140hp | 139 → 170 hp | 175 → 235 Nm |

Tuned figures are typical estimates from this model's gains; actual results depend on variant, fuel and supporting hardware, and are verified from your logs.
