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 ! 🧽🫧

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.

Neville’s WK Grange came in with what sounded like a nice, simple plan…

Full exhaust, OTR and a tune.

Then, as these things tend to do, one job became another… then another… and before long Neville had pretty much ticked the “while you’re there” box on half the car. 😂

What followed was a proper freshen-up and upgrade package, including a camshaft upgrade kit, cam bearings, valve springs, pushrods, ARP hardware, fresh gaskets and seals, suspension and steering repairs, differential servicing, ignition components, general repairs and plenty of attention to the little things that make the whole car feel right again.

The end result is exactly what we wanted a much happier WK Grange that drives better, performs better and is now in a far better place than when it first rolled through the door.

Finished off with the full exhaust, VCM OTR and a custom hub dyno tune, Neville’s Grange went on to produce a healthy 378.4 HP at the hubs with 478.1 dNm.

Neville himself was an absolute pleasure to work with from start to finish. Good laughs, great communication and complete trust in the process which always makes jobs like this even more enjoyable for us.

As always, we took plenty of pride in the workmanship throughout. Whether it’s a performance upgrade, a repair or something we discover along the way, the standard doesn’t change.

Do it once. Do it right.

Thanks again Neville — enjoy the Grange mate. It certainly left us a very different car to the one that arrived. 👌

Here’s another version of one of the most rewarding builds we’ve had through PSI. 💚

Adrian’s Mk1 Es**rt was a massive transformation from where it started — yellow paint, carburettors, RS-style wheels and factory trim — to the finished car you see here today.

Nearly 12 months of work, plenty of problem solving, fabrication, changes along the way and a fair few “while we’re here…” moments 😂 but the end result made every bit of it worthwhile.

A huge thank you again to everyone who played a part in bringing this car together:










And a special thank you to Cherie from for the editing skills on this reel and for helping us capture this build properly. 🙌 You’ve absolutely nailed it.

Building this Es**rt for my cousin made the whole project that little bit more special. One hell of a transformation, one hell of a journey, and definitely a build we’re proud to have our name on. 💚🏁
