Why more Adelaide drivers are
choosing Stealth Installs
Our focus is understanding the vehicle first, then delivering a calibration that's backed by data, mechanical expertise and ongoing support.
Vehicles are assessed at the start
Not every vehicle should be tuned immediately. We identify mechanical issues first so your calibration starts with a healthy foundation.
Tailored solutions
It's not one-size-fits-all. Every tune is developed around your vehicle, its modifications, and how you're actually going to drive it.
Results backed by real vehicle data
We provide before and after measurements so you can see the outcome of your tune with confidence.
Ongoing workshop support
From diagnostics and servicing to 4WD upgrades, you're supported by the same team long after your tune is complete.
“We don't believe diesel tuning is just about uploading a file.
We believe it's understanding the vehicle first, calibrating it properly and supporting it afterwards.”
We're rarely the cheapest quote, and that's on purpose
You're paying for diagnosis before we touch anything, a qualified mechanic and auto electrician with 30+ years on these vehicles, new parts fitted properly, and a tune built around how you drive. We listen first, recommend only what you need, and stand behind the work.

From first enquiry to ongoing support, our process is designed to make sure every vehicle gets the right solution, not a quick fix.

Where required, we check the vehicle's health and carry out diagnostics before recommending next steps.
Complete the work
From mechanical repairs to diesel tuning and touring upgrades, all work is completed with care and attention to detail.
Test & verify
We perform final checks and testing where applicable to make sure everything is operating as it should.
Ongoing support
We're here after the job is done, for servicing, advice, and future upgrades.
