LS1 Mail Order Tuning Australia-Wide
LS1 Mail Order PCM Tune for VT, VX, VY and VZ Commodore & HSV
Oztrack offers mail-order LS1 PCM tuning for Holden Commodore and HSV owners throughout Australia.
LS1 engines respond particularly well to calibration changes, and we almost always see a clear improvement compared with the original factory tune.
Choose a tuned performance PCM on its own or combine it with one of the OTR intake packages in the product selector above.
LS1s Respond Extremely Well to Tuning
On healthy stock VT, VX and VY LS1 combinations, we commonly see around 25rwkW gained from tuning alone.
Some cars gain more and some less, but the improvement in throttle response, mid-range performance and overall drivability is normally very noticeable.
Fuel economy can also improve. In suitable vehicles we have seen improvements of up to around 15% compared with the original factory calibration.
LS1 Tuning Developed Since 2006
Oztrack has been tuning LS1 Commodores and HSVs since 2006.
Over that time we have developed LS1 calibrations through dyno testing, road testing, remote tuning and experience with a large range of stock and modified combinations.
Our mail-order tunes are based on this accumulated LS1 calibration data rather than an unknown generic tune file.
Oztrack LS1 Mail Order PCM
What Is an LS1 Mail Order Tune?
A mail-order tune allows you to upgrade the LS1 calibration without bringing the vehicle to Oztrack for a normal dyno tuning appointment.
We supply an LS1 PCM programmed with an Oztrack performance calibration. Once installed, the engine operates using the revised tune.
This service is best suited to common LS1 combinations where we already have extensive calibration experience.
Supported LS1 Holden and HSV Models
This service is intended for LS1-powered VT, VX, VY and VZ Holden Commodore and HSV applications using the LS1 PCM system.
- VT Commodore and HSV LS1

Tuned Performance PCM
The Oztrack LS1 mail-order calibration on its own for customers who already have their intake hardware or simply want the PCM tuning upgrade.
Tuned PCM with VCM OTR
Combines the tuned LS1 PCM with a VCM over-the-radiator cold air intake.
Tuned PCM with VZ OTR
Includes the LS1 mail-order tune with the VZ-style OTR intake package shown in the selector above.
LS1 Mafless Tuning
LS1 mafless tuning is commonly used with an over-the-radiator cold air intake.
Rather than relying on the factory airflow meter as the main load measurement, the calibration is configured around the mafless airflow strategy.
This removes the restriction of the standard airflow meter from suitable intake combinations and allows the calibration to be matched to the intake setup.
What Improvements Can You Expect?
We almost always see a solid improvement from LS1 tuning compared with the original factory calibration.
The factory tune leaves room for improvement in areas including ignition timing, fuelling, throttle response and overall engine behaviour.
On a healthy LS1, customers can normally expect stronger throttle response, improved mid-range torque and more power at the wheels.
Stock VT, VX and VY LS1 combinations commonly gain around 25rwkW from tuning alone.
Fuel economy can also improve during normal cruising. We have seen gains of up to around 15% in suitable LS1 vehicles.
Results vary with engine condition, fuel quality, intake, exhaust, transmission and other modifications.
Craig’s VT Clubsport LS1 — Stock Cam, Automatic
Craig’s VT Clubsport is a good example of how well a healthy LS1 can respond to tuning even with the standard camshaft and factory airbox still fitted.
Craig’s LS1 Combination
- VT HSV Clubsport
- 5.7L LS1
- Automatic transmission
- Stock camshaft
- Factory airbox retained
- Manta 3-inch cat-back exhaust
- 1 7/8-inch 4-into-1 headers
- High-flow catalytic converters
This is still a stock-cam LS1 using the factory airbox. The result shows why we place so much value on getting the calibration right. Exhaust improvements help the engine breathe, but the tune is what allows the combination to make proper use of those changes.
Mail Order Tune, Remote Tune or Dyno Tune?
Mail Order Tune
Best for stock and common bolt-on LS1 combinations where we already have extensive experience with similar setups.
A simple Australia-wide option when individual custom calibration changes are not required.
Remote Custom Tune
Better suited to camshaft upgrades, more modified engines or vehicles that may receive further changes later.
Dyno Tuning at Oztrack
Best when you can bring the car to our Penrith workshop and want the tune calibrated specifically to your vehicle on our Mainline ProHub dyno.

LS1 Mail Order Tune FAQ
Answers to the most common questions about Oztrack LS1 mail order tuning for VT, VX, VY and VZ Commodore and HSV.
How much is an LS1 mail order tune?
An Oztrack LS1 mail order tune starts at $550 for the tuned performance PCM. VCM OTR and VZ OTR packages are also available through the product options at the top of this page.
How much power can an LS1 gain from tuning?
On healthy stock VT, VX and VY LS1 combinations we commonly see around 25rwkW gained from tuning alone. The exact result depends on engine condition, fuel, intake, exhaust and other modifications.
Can an LS1 tune improve fuel economy?
Yes. We have seen fuel economy improvements of up to around 15% in suitable LS1 vehicles compared with the original factory calibration, particularly during normal cruising.
Which Holden and HSV models does the LS1 mail order tune suit?
The service is intended for LS1-powered VT, VX, VY and suitable VZ Commodore and HSV applications using the LS1 PCM system. If you are unsure whether your vehicle is suitable, contact Oztrack before ordering.
Do I need to bring my car to Oztrack?
No. This service is designed for customers anywhere in Australia. We prepare the tuned LS1 PCM and send it to you for installation, so the vehicle does not need to come to our Penrith workshop. Dyno tuning later is discounted for previous customers.
Is a mail order tune suitable for a cammed LS1?
For a camshaft-upgraded LS1, we normally recommend a custom tune or a remote custom tune rather than a standard mail order calibration.
See our LS1 Remote Tuning service if the vehicle cannot come to our workshop.
Is a mail order tune the same as a dyno tune?
No. A mail order tune uses our developed LS1 calibration data for known combinations. A dyno tune is calibrated specifically to the individual vehicle while it is tested under load. Our Dyno Tuning has helped us to heavily develop the mail order tunes.
If you can bring the vehicle to Penrith, see our VT–VZ V8 Dyno Tuning service.
Can I order an OTR intake with the tune?
Yes. The product selector above includes options for a tuned PCM with a VCM OTR kit or a VZ-style OTR package.
What information does Oztrack need before preparing the tune?
Tell us your vehicle model and year, transmission, engine size, intake or OTR, headers, exhaust, diff ratio and any engine modifications. Accurate information helps us match the calibration to your LS1 combination.
What if my LS1 is heavily modified?
Contact Oztrack before ordering. Larger camshafts, injector changes and less common engine combinations are normally better suited to remote custom tuning or an individual dyno tune.
Not Sure Which LS1 Tune You Need?
Tell us your Commodore or HSV model, transmission, intake, exhaust and engine modifications.
We can tell you whether the mail-order PCM or remote custom tuning service is the better choice.
