TunedNZ supplies custom ECU remap and tuning files for petrol and diesel vehicles—enhancing power, fuel efficiency, and drivability. Ideal for performance upgrades, economical tunes, and fleet vehicle optimization across New Zealand.

Economy Tuning

Increasingly popular with rising fuel prices, we are able to recalibrate the ECU data to improve fuel efficiency. The increase in torque will allow less gear changes and accelerator pedal movement thus resulting in improved MPG and drivability.

Stage 1 Tuning

Designed for a standard and unmodified vehicle with no hardware upgrades. A Stage 1 Remap increases power and torque while also improving fuel efficiency. Removes flat spots and gives a more responsive drive without compromising reliability.

Stage 2 Tuning

Bigger increase in power and torque than a Stage 1 Remap, efficiency will still improve but not as dramatically as a Stage 1 Tune. Often hardware upgrades are required before a Stage 2 Remap can be applied. Removes flat spots and gives a more responsive drive without compromising reliability.
