Bring your car to our dyno shop in Glendene, Auckland for a custom dyno tune. We start with a base dyno run and diagnostic check to establish existing power and torque. We then read your cars’ existing mapping and modify it, continually testing, measuring and refining for the best possible results. At the conclusion you’ll be provided with before and after dyno graphs so you can see the gains before you feel them! This usually takes a day and we have a loan car available. Bookings well ahead of schedule are essential.

Send us your ECU and we will remap it and send it back, usually within 24 hours (excluding freight time). Reinstall into your vehicle and instantly feel the results! Simply let us know if you need info on removal or reinstallation.

Do it yourself (DIY) with our handheld programmer – it’s actually really easy. You read the ECU via the vehicle’s diagnostic port and email the programme to us. We modify it and email it back. You then use the DIY programmer to rewrite the vehicle’s ECU. You keep the DIY programmer and have the ability to change between original and Tune Technic maps at any time – not that you’ll want to!
