PSI Performance

YOUR CAR HAS A HISTORY. NOW IT HAS A HOME. 🏁

The PSI Performance Garage app is live on the Australian App Store. This is your PSI workshop relationship in your pocket not another pile of invoices, forgotten service dates and photos you can’t find when you need them.

Download the app for free to keep your vehicles together, request bookings, track kilometres and stay on top of reminders. Review the PSI records available for your vehicle, from service work and recommendations to dyno results and invoices. Explore our trusted partners, plan your next build, and ask PSI to review your car if you’re thinking of selling it.

Want the complete organised vehicle archive? Performance+ is optional, with one subscription covering every vehicle in your PSI account. It brings your workshop photos, invoice copies, dyno files and supporting documents together especially useful when it’s time to show the care that went into your car.

We built this around the same things we bring to the workshop: detailed workmanship, duty of care, a real passion for cars and support after the job is done. Your car deserves a record that keeps up. Watch the walkthrough, then download PSI Performance Garage:

A new addition to the Cavallo garage, with the PSI treatment to match. 🔥🏁

Daniel Cavallo brought his GEN-F HSV Maloo into PSI Performance for MCA Pro Comfort coilovers front and rear, finished off with a wheel alignment to bring the whole setup together.

The result - Looking better than ace, with comfort taken to the next tier as well. 👌 A tough stance is one thing, but having the ride quality to match makes the whole package that much sweeter and that’s what we love about this MCA Pro Comfort setup. MCA Suspension

At PSI, we take pride in the details. From the products we fit to the care we put into the setup, it’s about helping our customers get more enjoyment out of their cars. This Maloo brings it all together: presence, comfort and a fresh setup ready for Daniel to enjoy.

A massive thank you to Daniel and the Cavallo family for supporting PSI and trusting us with the newest addition. Your support means a lot, and we’re proud to be part of the journey. 🤝

There’s something special about a generational business like Cavallo continuing to build on its legacy, going strong and setting the benchmark for other businesses. That ongoing commitment takes hard work, pride and support across generations, and it deserves recognition.

From our team at PSI Performance, thank you to Daniel and everyone who continues to book with us, recommend us and back what we do. Those relationships help our business grow, and we never take them for granted.

Enjoy the Maloo, Daniel looking the part and feeling even better. 🔥Shout out to Chris from Elite Car Detailing Studio for doings gods work to this before it came to us ! 🧽🫧

Fun day with Melbourne today . .pugliese
+ many more . The mighty VL getting into stage 3 Elims hahaha killed it 🍀🎁

Today is a reminder of something that should matter every single day.

R U OK?

It’s such a simple question, but sometimes it can be the question somebody really needs to hear.

We live in a world where it’s very easy to say “I’m fine”, put on a smile, go to work and carry on. The truth is, we often have no idea what the person beside us is dealing with behind closed doors.

So ask the question, and don’t just ask it because today tells us to.

Actually listen to the answer.

If something doesn’t seem right, ask again. Sit down with them. Make the phone call. Send the message. Have the uncomfortable conversation. Give someone your time and listen without judgement.

You don’t need to have all the answers. Sometimes just being there, listening and letting someone know they have somebody in their corner can mean more than you’ll ever realise.

At PSI, cars are our passion and our business, but at the end of the day people will always matter more than cars, horsepower or anything else that comes through our doors.

Look after your mates. Look after your family. Look after the people you work with. And don’t forget to check on the person who always seems to be the strong one too.

If someone comes to mind while you’re reading this, message them. Call them. Go and see them.

Don’t assume somebody else will.

A genuine conversation might make a much bigger difference than you realise.

Ask. Listen. Be there. Check in.

💛 R U OK?

Michael’s Caprice came in for a little more choice and a lot more character. 🔊 - watch the videos and have a listen ! 📣🚨🎼👀

We supplied and fitted a Varex controlled rear muffler system, giving Michael the option to keep the Caprice civilised when required or let the V8 speak with considerably less supervision when the moment is right.

While it was with us, and as Michael always does, he gave us the go ahead to take care of several serviceable items requiring attention. Nothing unnecessarily dramatic just the honest maintenance and mechanical details that help keep the Caprice hugging the road and behaving exactly as it should.

Michael isn’t simply a repeat customer. He is a genuine friend, a valued supporter and very much part of the PSI family.

Thank you again, Michael, for your continued trust, loyalty and friendship. We genuinely appreciate the people who continue to support us—and we will always look after the people who look after us.

Quiet when you want it. V8 when you don’t.

New state, new plates—and a proper Melbourne welcome. 🇦🇺

Dilu recently brought this VE GTS to PSI Performance after purchasing it in Adelaide and bringing it across to Victoria.

Before it could be registered here, it needed to complete the Victorian roadworthy process. We carried out the RWC inspection and worked through the required repairs and maintenance, including:

• New rocker-cover gaskets
• New engine mounts
• Brake-fluid flush
• Replacement power-steering cap
• Several additional minor items requiring attention

Nothing wild—just the important mechanical details handled properly so Dilu could move forward with the Victorian registration process confidently.

A very tidy VE GTS, now officially welcomed from South Australia to its new home in Melbourne.

Thank you, Dilu, for trusting PSI Performance with it.

Do it once. Do it right.

From Maloo to GTS… apparently Chris has decided two doors simply weren’t enough. 😂

Our good friend Chris from Elite Car Detailing Studio recently brought in his newly purchased VF GTS a proper five-seat, four-door, LSA-powered sedan after recently moving on from the VF Maloo we had also worked on for him.

He’s only owned the car for a couple of weeks, but unfortunately it needed a little more attention than expected. Even more surprising considering it had recently been supplied with a RWC… 🤔😥

We carried out a full health and safety inspection, including a compression test, complete vehicle once-over, fluid and maintenance checks, and a detailed assessment of the areas that needed attention. From there, we worked through as many of the concerns as possible within Chris’s very tight schedule and completed the additional maintenance and repairs he elected to have done while the car was with us.

Once the mechanical side was where we wanted it, it was onto the Mainline hub dyno.

And the difference from tuning alone was certainly worth talking about.

The final result was 613.8 HP @ 5,664 RPM and 1151.2 dNm @ 2,419 RPM, with a much healthier, stronger and more refined package than what arrived.

Chris, thank you again for the continued support, the business, the trust, and for being such a valued partner of PSI. You also somehow manage to make every visit entertaining… usually at our expense. 😂

Enjoy the new family-friendly LSA weapon mate because apparently “practical” now means supercharged V8 sedan.
