Renault, Nissan & Mitsubishi Performance Tuning Auckland

Renault, Nissan, and Mitsubishi vehicles bring together everyday practicality, Japanese and European engineering know-how, and serious performance potential. At Auto Upgrades, we specialise in unlocking that potential through precision ECU remapping and transmission calibration. Using OEM-level tuning methods, we deliver gains that feel seamless, safe, and reliable—like they came from the factory, only better.
