VE Commodore V8 Power Upgrades
|
Fuelled by their success in the battlefields of V8 Supercar racing, Holden’s VE model range represents the current pinacle of Holden V8 performance. Benefiting from GM’s impressive LS2 and LS3 engine packages, the VE range represents amazing value straight off the showroom floor. The good news is that Holden left a lot of untapped potential in these cars, and STM offer several options to extract this potential and gain massive improvements in power and torque while realising gains in fuel economy at the same time!
STM have developed a simple upgrade system specifically for the VE Holden platform. Our upgrades focus on improving torque and power throughout the engine’s rev range, without sacrificing driveability or reliability. Our staged upgrades allow you to modify your pride and joy with the confidence of a tested and proven result. With our staged upgrades, you can choose the upgrades that match your requirements as well as your budget.
While all our stated power figures are from real life case studies,these should be considered indicative only. Individual results may vary from car to car.

 Overview
STM’s 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.

 Overview
STM’s 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. STM’s 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.

 Overview
STM’s Stage 2 upgrade is aimed at customers who are looking to get the most power and torque from their engine with bolt-on upgrades. STM’s 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 LS2 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.

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.
