Truck and Bus Tuning

Whether you want higher power, more torque and smoother gains across the rev range, a broader power band, or simply better fuel economy then NZ Performance Tuning have the knowledge and capability to shape your engines characteristics around the way you drive.

All of this is done by working with, instead of against the original vehicle systems. The vehicle can be completely returned to its original state at any time.

NZ Performance Tuning is the answer for the customer who cares about performance and quality. We do not change settings to dramatic levels or use boost spiking for that ‘feels quick’ effect, where in reality performance would be lowered where an ECU can adapt out these dangerous levels. Instead we tailor many changes throughout the rev range altering many perimeters – others neglect to give optimal performance throughout.

NZ Performance Tuning offers a large range of power upgrade options for modern ECU controlled trucks. Having a NZ Performance Tuning remap onto a truck, you will immediately see an improvement in power, torque and fuel efficiency. You will notice more torque making it easier to pull up steep inclines, more power to tow the heavy loads, but above all you will use less fuel which depending on your usage could be saving thousands of dollars per year!

Will my truck be out of service?

Most of the time we perform all work on site, so the tractor is not out of action for any time at all.

We have dealers that service most corners of the country! Using the latest tooling and hardware, we are able to perform the upgrades on the vast majority of vehicles without needing to remove the ECU.
