What if the massive peak power figure on your dyno sheet is actually masking a car that’s sluggish and unpredictable on the street? It’s a common frustration for many owners who find their vehicle delivers inconsistent power or feels "off" after a session on a traditional roller dyno. We know you want more than just a glory run; you want a machine that responds instantly every time you hit the throttle.
At Oztrack Performance, we specialise in dyno tuning penrith enthusiasts trust to deliver real-world results. With over 10,000 vehicles tuned, Steve and Jonathon understand that true performance comes from precision calibration, not just chasing a number.

Why Mainline ProHub Dyno Tuning is the Gold Standard in Penrith
Dyno tuning is the technical process of recalibrating your Engine Control Unit (ECU) to perfectly match your engine’s hardware and fuel quality. To understand the basics, you can read up on what a dynamometer is and how it measures force. We perform this precise calibration at our dyno tuning penrith workshop, located at Unit 8, 28 Coombes Dr. Our facility is built around the Mainline ProHub because it provides the most accurate data available to enthusiasts today.

Roller Dynos vs. ProHub: The Real-World Difference
Traditional roller dynos have a major flaw: tyre slip. When you’re pushing a high-torque LS engine, the tyres can lose traction on the metal rollers. This skews the data and creates inconsistent results. Factors like tyre diameter and air pressure can effectively "cheat" the numbers, giving you a reading that doesn’t reflect reality.
The Mainline ProHub connects directly to the vehicle’s axle hubs. This setup eliminates tyre slip entirely and ensures 100% repeatable accuracy. It’s also a much safer method. There’s no risk of a car jumping off rollers or sustaining tyre damage from excessive heat soak during a pull. We focus on dyno tuning penrith drivers can rely on for the street, not just a peak number on a piece of paper. For a deeper look at why hub-based measurement delivers superior results, read our full breakdown of ProHub dyno accuracy and the myths of hub vs roller tuning.
The Oztrack Experience: 10,000+ Vehicles Calibrated
We’ve calibrated over 10,000 vehicles since we started in 2006. Steve’s background in drag racing. Teamed up with Jono and Dan who both have vast experience in circuit racing experience and engine development. We know how to push boundaries without compromising engine longevity. We maintain a strict customer-first philosophy.
We provide a crisp, responsive calibration tailored to your specific modifications. Whether you’re after VE-VF V8 tuning or a complex LSA setup, our experience ensures your car performs exactly as intended. We take pride in delivering results that improve the entire driving experience from idle to redline.
Custom Calibration for LS, LSA, and Ford Performance
A performance part is only as good as the software controlling it. When you install a VCM OTR intake, you change the air-to-fuel ratio significantly. Without a custom tune, your ECU will struggle to compensate, leading to poor fuel economy or even engine damage. We provide the **dyno tuning **owners need to ensure every modification works in perfect harmony with the engine’s factory sensors.
Our expertise extends beyond Holden platforms to include Ford Mustang Gen 2, Gen 3 and Gen 4. As well as the legendary XR6 Turbo and XR6 or XR8 models.
LS Camshaft Upgrades and Dyno Synergy
Fitting a cam upgrade is the most popular way to transform a Commodore. However, a large cam can make a car difficult to drive at low speeds. We spend hours on the hub-dyno perfecting idle stability and off-idle response. Jonathon, our Leading Technician, ensures the mechanical installation is flawless before Steve begins the software work. For VF Commodore owners, we can even dial in a "lumpy cam" sound that provides that aggressive idle without sacrificing safety or drivability.
LSA and Supercharged Packages
For those chasing serious power, our VF LSA performance packages and Harrop supercharger setups are designed for maximum impact. Managing heat and fuel delivery is critical when you’re targeting 500rwkW or more. We monitor every parameter to ensure the engine stays within safe operating limits even under heavy load. A high-performance build is only as reliable as the calibration that controls it. Before any serious power build, it’s worth ensuring your block has been through proper LS engine machining — precision boring, honing, and sleeving are the invisible foundation that determines whether your investment lasts. If you’re ready to see what your V8 is truly capable of, consider booking a session for VE-VF V8 tuning today.
Your Dyno Session in Penrith: What to Expect
Walking into our workshop at Unit 8, 28 Coombes Dr, you’ll find a clean, organised space dedicated to precision. You can watch the tuning on two big TVs in our lobby.
Each car is tuned by a team of two. One car operator and one laptop operator who work together.
If you can’t make it to our facility, we offer Australia-wide remote tuning kits to bring our calibration expertise to your garage.
During the session, we log every variable in real time. You’ll receive a printed dyno graph showing your gains in kW. We don’t hide behind inflated numbers. Our database can compare all of our cars and as at June 2026 it has 780 cars in this prohub dyno since early 2023.
The 5-Step Oztrack Tuning Process
Mechanical health check: Verification of fluids, plugs, and leads to prevent failures.
Baseline run: Establishing your car’s current power levels before any changes.
Incremental adjustments: Fine-tuning ECU tables for fuel, spark, and cam timing.
Drivability simulation: A final ProHub test to confirm perfect street manners and gear shifts.
Post-Tune Support and Maintenance
High-performance calibration requires proper upkeep. We recommend shorter spark plug gaps for modified V8s to ensure a strong spark under load. Using 98 RON fuel is non-negotiable. Lower octane fuels will trigger knock sensors and pull timing, killing your performance. We store your specific tune file securely in our database. This allows us to easily update your calibration if you decide on further modifications down the track.
Precision tuning is the only way to truly enjoy your modified vehicle. Don’t settle for a generic map that compromises your engine’s longevity. Book your Penrith dyno session ONLINE with Steve and the team today and experience the Oztrack difference.

Frequently Asked Questions
How much extra power (kW) will I get from a dyno tune?
Power gains depend entirely on your current hardware and fuel quality. A stock LS V8 might see an increase of 20 to 40 rwkW just by optimising the factory fuel and spark maps. If you’ve added a VCM OTR intake or a full exhaust system, the gains are much higher because the tune allows the engine to breathe properly. We focus on safe, repeatable power that doesn’t stress your components.
Is dyno tuning safe for high-kilometre LS engines?
It is safe as long as the engine is mechanically sound. We perform a thorough pre-dyno inspection to check for leaks, valvetrain noise, or cooling issues before we start. High-kilometre LS engines are remarkably resilient, but we won’t push an engine that shows signs of excessive wear. If you’re planning a rebuild, starting with professional LS engine machining including boring and honing ensures your block can handle the power we’re about to calibrate for. Our dyno tuning service prioritises longevity over "hero" numbers that could cause a failure.
How long does a full custom dyno tune take at your Penrith workshop?
A comprehensive custom tune typically takes between two and three hours. This isn’t just a couple of power runs; it involves calibrating the idle, part-throttle cruising, and wide-open throttle performance.
Can you tune my car if I live outside of Sydney or Penrith?
Yes, we support enthusiasts Australia-wide through our remote tuning kits. We use the AutoCal V3 system to send custom calibrations to customers in regional NSW, Queensland, and beyond. You record data logs while driving, send them to us, and Steve adjusts the tune until it’s perfect. It’s the same high-quality calibration we offer for dyno tuning penrith at our local workshop.
Do I need to install a cam or exhaust before I get a dyno tune?
You don’t need modifications to see the benefits of a tune. Even a completely stock vehicle benefits from improved throttle response and improved torque across the range.
