About Auckland Diesel Tuning
Part of the Auckland Automotive Group
Our Story
Auckland Diesel Tuning was founded with a single mission: to provide the highest quality diesel performance tuning in New Zealand. What started as a passion for getting the most out of diesel engines has grown into Auckland's most trusted diesel tuning workshop.
With over 5,000 vehicles reflashed and counting, we've built our reputation on delivering consistent, reliable results that our customers can feel from the moment they drive out of our workshop. Our average power increase of 35% and torque increase of 45% speak for themselves.
As part of the Auckland Automotive Group, we have access to a wide network of expertise and resources — allowing us to offer a comprehensive service that goes beyond just ECU remapping.
