Looking to increase the performance or fuel efficiency of your diesel engine? The Performance Shop, a division of The Workshop 1924, can help you unlock more power, torque, and fuel efficiency from your vehicle with professional ECU remapping and emission system solutions.
We specialise in custom diesel tuning for trucks, tractors, utes, and agricultural machinery in Auckland.
What is ECU remapping?
Modern vehicles are controlled by an Engine Control Unit (ECU) programmed with conservative factory settings to suit global conditions. ECU remapping involves professionally modifying this software to optimise performance for New Zealand conditions, fuel quality, or your specific use case.
At The Performance Shop, we customise every ECU remap so your vehicle performs exactly how you need it. Whether you need increased pulling power, improved fuel efficiency, or better drivability, we've got you covered.
You can learn about the process of ECU remapping here.

What are the benefits of ECU remapping?
Our ECU remaps are designed to improve both performance and efficiency, not just power. An ECU remap can provide:
- Increased horsepower and torque (typically 20 – 35%)
- Improved fuel efficiency (up to 6 – 13% in some cases)
- Better towing and load performance
- Smoother driving and throttle response
- Reduced engine strain when tuned correctly
How much does an ECU remap cost?
Our ECU remaps typically range from $900 to $3,500 + GST, depending on vehicle type and requirements. We provide fixed quotes upfront so you know exactly what to expect.
