Opel specialists · TullamarineOpel tuning in Tullamarine, Melbourne
Opel stopped selling new cars in Australia years ago, but there are still plenty of Astra OPC, Corsa OPC and Insignia owners around Melbourne who want to keep them sharp. We tune Opels at our Tullamarine workshop with honest advice on what is realistic for an older, less common car.

Performance upgrades for your Opel
Realistic tuning and upgrade work for Opel owners.
OPC ECU calibration
Software for the turbo petrol engines in the Astra OPC and Corsa OPC where our tools support the ECU, calibrated on our dyno with the original file saved first.
Insignia OPC and turbo petrol tuning
Calibration for the Insignia OPC V6 turbo and the four-cylinder turbo models where supported. We confirm compatibility for your exact car before booking.
Exhaust systems
Cat-back exhausts for the OPC models that add character without crossing VicRoads noise limits.
Intake and cooling
Intake and intercooler improvements help a turbo Opel hold power consistently in warmer weather.
Suspension refresh and upgrades
Many Opels are now at the age where dampers and bushes are tired. Fresh suspension or coilovers often transform how the car drives.
Brakes
Pad, fluid and rotor upgrades, especially worthwhile on an OPC used for spirited driving or the odd track day.
Build your Opel in stages
Start where it makes sense for your car and budget, then build from there. Every stage is calibrated in-house.
Software only on a healthy, standard turbo Opel where the ECU is supported. Our first recommendation for most OPC owners.
Software matched to exhaust, intake and intercooler upgrades. Parts availability varies for these cars, so we source and confirm before quoting.
Turbo and fuel upgrades are possible on some OPC builds but are rare and planned case by case. We will be upfront if it does not make sense for your car.

We use Magicmotorsport professional tools to read and write Opel ECUs where supported, always keeping a backup of the original software. Some Opel-built Holden models may also be supported, and we check each car individually.
Before you tune your Opel
Condition comes first
Most Opels on the road here are now well over ten years old. We do a full health check, fault scan and data log before tuning, and we will recommend any repairs first.
Parts availability
With no new Opel sales in Australia, some performance parts have to be imported. We confirm availability before you commit to anything.
Clutch and drivetrain
A worn clutch will often slip once torque increases on an OPC. We check it during the inspection and talk about options.
98 RON fuel
Turbo Opels should run on 98 RON premium unleaded after tuning, and ideally before.
Opel tuning questions
Yes, where our tools support the ECU. Opel left the Australian market, but the cars are still here and the OPC models in particular respond well to sensible calibration.
Several Holden models were built by Opel in Europe. Tell us the model and year and we will check whether its ECU and parts are supported.
After a health check, Stage 1 software is usually the best value, followed by suspension and brakes. It depends on the car's condition and how you use it.
Yes. We service and repair European cars at our Tullamarine workshop, and getting the car healthy is the first step before any tuning.
