Looking for simple upgrades like more of that iconic Holden V8 sound or do you want to get the absolute most out of your Commodore or HSV?  Our Holden Upgrade packages offer a range of options to suit all needs.  Our packages are designed to give you the best bang for buck options available and in most case are totally reversible. 

Stage 0 upgrade is aimed at customers who are looking for a moderate improvement in power and torque without the need for bolt-on parts. We retain all the factory hardware, and simply remap the factory ECU to optimise the Fuel and Ignition mapping to get the best performance from your engine. For vehicles equipped with automatic transmissions, we are also able to optimise and refine the transmission behaviour to improve response and crispness of shifts. All our upgrades are custom-mapped by our professional tuner on our in-house chassis dyno.

Stage 0 will suit

  • Customers who want a moderate gain in performance without the need for aftermarket bolt-on parts
  • Customers who want a totally undetectable upgrade
  • Customers wanting to retain the stock exhaust note

Stage 1 upgrade is aimed at customers who are looking for a big gain in power and torque, while also improving the sound of their car. In stock form the strangled factory exhaust doesn’t do justice to GM’s race-bred V8 engine. Our stage 1 upgrade rights the factory wrongs with a high quality mild steel exhaust system that unleashes that V8 roar of your engine.

In addition to a replacement exhaust system, we remap the factory ECU to optimise the Fuel and Ignition mapping to get the best performance from your engine. For vehicles equipped with automatic transmissions, we are also able to optimise and refine the transmission behaviour to improve response and crispness of shifts. All our upgrades are custom-mapped by our professional tuner on our in-house chassis dyno.

Our Stage 1 upgrade can be performed in a single day, and we can even do the work while you wait.

Stage 2 upgrade is aimed at customers who are looking to get the most power and torque from their engine with bolt-on upgrades. Our stage 2 upgrade package has been carefully selected to optimise every aspect of the engine’s performance without needing to change internal componentry. This represents the absolute best value for money approach to modifying your LS engine!

Our Stage 2 Package includes a full mild steel high-flow 2.5" exhaust system including headers, and adds an over-the-radiator intake kit to provide your engine with lung fulls of clean cool air. These modifications require a special MAFLESS tune which allows the factory MAF to be removed from the intake. An over-the-radiator intake is the perfect way to dress up your engine bay while adding performance. For vehicles equipped with automatic transmissions, we are also able to optimise and refine the transmission behaviour to improve response and crispness of shifts. All our upgrades are custom-mapped by our professional tuner on our in-house chassis dyno.

Our Stage 2 upgrade requires two days to complete.

At this point, we have exhausted the potential of the factory engine, and more performance means removing some of the factory restrictions in your engine. Stage 3 upgrades are tailored to your individual requirements, and we will select a suitable combination to achieve your power aims, while meeting your budget. Typical Stage 3 upgrades consist of replacing the lazy factory camshaft with a specially ground performance cam. The upgraded camshaft is complimented with a set of uprated valve springs. Our Stage 3 Package includes the same mild steel high-flow 2.5" exhaust system from our stage 1 and 2 packages, as well as the over-the-radiator intake kit. For vehicles equipped with automatic transmissions, we are also able to optimise and refine the transmission behaviour to improve response and crispness of shifts.
