This product is a performance MAF tune to suit all Holden models VT up to VZ equipped with a 5.7L V8 including Commodore, Calais, Statesman & HSV models. Unlike some others available on the market, this tune has been developed using data collected from numerous dyno and street tunes that we have performed to provide a significant power increase for these engines.
The tune is provided to you ready to install on an exchange computer (PCM) we have in stock. Once you have installed the provided computer and are satisfied you simply send your original back to us. Alternatively you can choose to keep your original computer if you wish although the deposit will not be refunded (see below). We have numerous computers already in stock to avoid long delays between customer transactions. Otherwise if you wish you can send your original computer to us for re-programming.
Huge Power Increase!
When used in conjunction with a good exhaust system, typical power output that can be expected is between 225-240kw at the wheels with significantly increased torque across the rev range. This equals over 300kw at the engine up from the standard 220kw provided from factory. The results are achieved through the recalibration of both ignition timing and fuel mapping. The end result is a greatly noticeable performance increase that pushes you back in your seat and reduces acceleration times greatly. Fuel economy should not be affected through the use of this recalibration and in some circumstances an improvement in fuel economy can be seen.
Tuned For Mass Airflow Sensor (MAF).
This tune has been set up for MAF operation which enables you to keep your air flow sensor (MAF sensor). If you wish to purchase a performance tune to remove your MAF sensor please see our other items for a Mafless Tune (recommended when running an OTR/Over The Radiator Intake).
Improved Automatic Shifts!
In addition to the performance gained from the increased output power, in automatic vehicles the transmission shift pressures have also been increased slightly to improve transmission shift time & firmness therefore improving the performance and feel of the vehicle.
Easy To Install Yourself!
The tune is provided to you ready to install on an exchange computer (PCM) we have in stock and detailed installation instructions with pictures are provided. Installation typically takes 30mins and requires only basic tools.
Customised For Your Car!
When you purchase a tune from us we first discuss what modifications your car has and modify our base tune to best suit your vehicle. This increases performance and reduces the risk of damaging your vehicle.
Want More Power?
More power can be achieved through the use of other performance parts such as a cold air intake (around 5-10kw) and our high ratio roller rockers (20kw). The dyno graphs 255rwkw depicts a car that had all these items fitted. We sell these items and more and also offer performance packages which provide discounts if you wish to purchase several items.
Dyno Tuning & Installation Service
If you require dyno tuning for increased performance or for a heavily modified vehicle we can provide this for an additional cost. Also we can offer installation of our off the shelf tunes for an additional fee if you are located within Sydney or the Central Coast. Please contact us at for more information.
A deposit of $250 must be made on top of the final price to ensure the safe return of the original engine computer. Once this is returned the $250 will be refunded. You can choose to keep your original computer if you wish although the $250 will not be refunded. The $250 deposit is available from our other items.
When running these high performance tunes we recommend you try run a minimum of 95 Octane Premium Unleaded and where possible 98 Octane. Although it is safe to run standard 91 Octane unleaded if other alternatives are not available, it is advised that you should avoid heavy acceleration to protect your engine. .
