OC Tuned Vehicles


About Us

  • A VAG tuning enthusiast-turned Custom-Code dealer, Gavin has been driving and modifying VAG performance vehicles in the UK since the early 1990s. Prior to moving to Australia in 2006. Gavin purchased a 1.8T Seat Leon Cupra and sought to tune the vehicle. Upon the recommendation of a friend in the trade, he had it tuned by Custom-Code, and was so impressed with the results, that he decided to become a dealer himself – thus OptimumCode was born.

    Since then OptimumCode has been servicing various performance VAG vehicles as the sole Custom Code dealer in Australia. As a former UK resident, Gavin maintains a close working relationship with Custom-Code  HQ in the UK and provides the latest tunes and updates direct to Australian customers. Tuning is mostly done via OBD (diagnostic) port and thereafter fine-tuned with a road test and VAG-COM logs to ensure the best running conditions.

    OptimumCode is located just North of Brisbane in Queensland. However, as the only Custom-Code dealer in Australia, interstate tuning opportunities may be available depending on location and timing. Please feel free to contact us to discuss details.
