Warranty-friendly calibration workflows

Our core services

From mild drivability boosts to full staged performance builds, we apply engineering rigor to every job.

ECU Remapping

Custom maps tailored to fuel, local altitude, and component changes — tested on our dyno for repeatable results.

Turbo & Boost Works

Turbo upgrades, actuator calibration, and safe boost targets for NZ conditions.

Aftermarket Integration

Supporting throttle bodies, intakes, intercoolers and exhaust systems with proper corrections.

Dyno Validation

4WD dyno runs to validate power, torque curves and to ensure safe, compliant maps.

Our promise

Transparent reporting, conservative reliability margins, and clear upgrade roadmaps for each vehicle.

How we work

A structured process ensures performance gains without compromise.

Full scanner read, health checks, and a baseline dyno run to quantify the starting point.

Iterative map changes, road testing, and dyno validation until the target curve and drivability are achieved.

Delivery includes dyno logs, recommended service intervals, and remote support for follow-ups.

Technical highlights

Dyno	4WD inertia dyno, kW & Nm calibrated
