PSI PERFORMANCE · PAKENHAM
Have a car problem no one has pinned down?
Bring us the symptoms, what has been tried and what you want from the car. At PSI Performance in Pakenham, we work to find the cause, explain the options and carry out the agreed work with care.
Do it once. Do it right.
From everyday servicing and mechanical repairs to hub dyno tuning and full performance builds, our workshop looks after the whole car — and the person behind the wheel.

THE PSI APPROACH
Answers first. Parts second.
A warning light, misfire, strange noise or a repair that has not held up can be frustrating. We start by listening, inspecting and testing. Then we explain what we found, what matters now and what can wait. We recommend work for a reason, rather than swapping parts and hoping one fixes it.
If another workshop has not resolved the issue, tell us what has already been checked or replaced. That history helps us plan the next diagnostic steps; it does not replace our own assessment.
WORKSHOP SERVICES
Service to serious builds. One workshop.
Hub dyno tuning and performance
Measured tuning, drivability work and performance upgrades for naturally aspirated, turbocharged and supercharged setups. We plan around the car's hardware, fuel and intended use.
Engine builds and vehicle technology
Engine builds and rebuilds, head and cam packages, supported module coding and technology upgrades. We consider the complete combination, not just a parts list.
EV and hybrid servicing
We also service electric and hybrid vehicles, including maintenance and battery diagnostics where supported. Tell us the make, model and concern so we can confirm the right scope. See our EV and hybrid services →
