Mick and the team were great with the electrical diagnostics on my Subaru. They have done an awesome job of tracing down the issue.
Great staff & service — Subaru experts. Knew exactly what my car needed and got it done.
Incredible guys and mechanics — thank you for sorting my Subaru out. Honest, fast and properly priced.
WRX stage 2 tune with the intake, exhaust and TMIC. Mick built a custom map on the dyno — before/after graph, AFR/timing dialled, safe on 98. Feels like a different car. Best tuner in Perth.
Forester XT was flat off boost. Dyno pull showed a leaky BCS, Mick fixed it and retuned it — full torque back everywhere. Honest workshop, transparent data, workmanship guarantee.
Built STI needed a proper tune after the top-mount install. In-house dyno, custom map, road tune to finalise — every session logged and shared. Zero drama. Proper job.

Frequently Asked Questions
Everything you need to know before booking your Subaru in.
A dyno lets us hold the car at load while we adjust the ECU map — safely dialling in fuel, timing, boost and other parameters to extract power without risking the engine. Off-dyno tuning misses the load conditions where problems appear. If you've added a turbo, exhaust, intake, injectors or built the engine, the factory map isn't optimal — a proper dyno tune is the difference between safe reliable power and a blown engine.
A retune modifies the factory ECU calibration — for cars still under new-car warranty, it may affect the drivetrain warranty depending on Subaru's stance. We're upfront about that before we start. For most tuning customers this isn't a concern (car is out of warranty, or the owner has weighed the trade-off knowingly). Australian Consumer Law protects your right to service anywhere licensed — but a modified ECU is a different question. Ask us and we'll talk you through it.
All of them where a tune adds real value: WRX (every generation), STI, Forester XT/2.5XT, Liberty GT, Levorg, Outback XT and Impreza turbo variants. Built engines, aftermarket turbos, factory hardware — all handled. If you're unsure whether your Subaru is worth tuning, tell us the build and we'll be honest with you.
Stage 1 is an ECU-only tune on factory hardware — safest power gain, works with 98 pump fuel. Stage 2 adds bolt-on hardware (intake, exhaust, intercooler upgrade, injectors) and a matching map. Stage 3 is a fully-built engine with aftermarket turbo, forged internals, uprated fuelling — bespoke map development from scratch. We'll recommend the right stage for what you're actually going to use the car for.
A standard stage 1 or 2 tune is usually done in a day — baseline, iterative dyno pulls, road tune, final graph. Fully-built stage 3 or custom map development can take 2-3 days depending on the complexity. We'll always give you a realistic timeframe before starting.
Depends on the stage, the hardware and the complexity. Tell us your model, what's been added and what you want out of it, and we'll quote up front — fully itemised, no surprises. Every quote includes the dyno session, the map, the road tune and the final graph.
