The prices listed on the website include reading the ECU and writing the tuned ECU strategy to the car for any tune purchased from Auto Upgrades if you live in the Auckland area. If you live outside of the Auckland area, please call us before buying a tune so that we can arrange the logistics of the installation.

We will do our best to arrange the installation of the tune at a time that is convenient for you. Once your order is placed, we will contact you via phone or email to arrange a suitable time for installation. You may also call us prior to ordering and make a booking if you would like to reserve a specific time for no extra charge.


You may cancel your order and receive a full refund if you give 24 hours’ notice prior to the first installation appointment. If you cancel at any point in time after this you will be charged for any costs we incur including labour and travel. We will not charge you any administration costs for cancellation.

Performance Guarantee:

We guarantee that we will improve the performance of your vehicle with respect to responsiveness, power and torque gain as well as fuel economy, if you feel that we have not done so, please contact us within 7 days and we will either resolve matters to your satisfaction or return the vehicle to the original tune and refund the cost of the tuning.

Previously tuned cars:

If your car has been tuned previously we will investigate whether it is possible to improve the tune that is programmed into the car. After the engineering investigation, we will either retune the vehicle as normal or advise you to keep the existing tune where appropriate, you will not be charged the cost of tuning in this case but you will be charged for testing work at our normal hourly rate. We may not be able to return the vehicle to a factory tune if required if a software change has been made by a previous tuner.


There are some risks involved with reprogramming your vehicles ECU and with the running the modified ECU tune. We will do everything we deem practicable to mitigate these risks including rigorous diagnostics testing, checking the Air/Fuel ratios both via Live Data from the ECU (where available) and from a sensor that is attached to the exhaust using a special clamp. We will also monitor the combustion noise and monitor other relevant available Live Data from the ECU such as boost pressure (both desired and actual if available) to establish as far as is possible from this testing that everything is running safely. However, some things may be outside our control including, but not limited to, vehicle maintenance issues or undetected prior engine or turbo damage, undetected defects such as an ECU power supply or memory fault. You agree to indemnify and hold harmless Auto Upgrades, Ecommerce NZ Ltd, and each of their respective directors, shareholders, employees, and agents for all associated Losses arising from any problems that may occur from tuning your vehicle. We will work with you to fix any problems that could occur, however, there could be delay and cost associated with this process. It may take longer than normal if any problems occur or maintenance work is required to support the tuning, feel free to ask any questions we will be happy to explain any aspects in detail and will keep you informed.
