Trusted diagnostics. Thorough repairs. One happy customer ⭐

This van came in for an intake clean, but our checks uncovered a few issues needing attention. Cam and the team got it sorted:

• Intake manifold replaced
• Damaged boost hose replaced
• Coolant leak repaired
• Service completed

Clear explanations and video updates kept Shaun informed along the way and he was stoked with the result!

Thanks for the 5 star review, Shaun and for trusting us with your work van. A big shoutout to Cam and the team for the thorough work behind it! 👏

You fill it. You drive it. Are you getting the best out of it? ⛽

Anyone can plug in a laptop. 9 years of dyno tuning 4x4's is what makes the difference.

We tune your rig on our in-house dyno, not by guesswork, so you can see the real results! Smoother power, better performance and improved fuel economy.

How do we know it’s school holidays? The workshop fills up with buses! 🚌 A break from the school run means it’s time for us to get to work. Keeping local buses ready for the road and the busy term ahead 💪

The Chevy builds keep coming.

This 2500 received a 3-inch BDS suspension lift with FOX remote reservoir shocks, fitted to the manufacturer’s specifications. We followed it with an in-house laser wheel alignment to dial in the setup for the road.

The work didn’t stop at the lift. We also completed its logbook service, fitted the UHF antenna and handpiece bracket, and replaced both front wiper arms.

Another Chevy is already in the workshop. We’ll show you that one soon. 👀
