Commodore 6's

A very popular model for performance optimisation is the trusty Commodore six cylinder. Now in most workshops your options for performance upgrades may not be that great, but not at Towlers! Here we use the latest computer hardware and software from Delco and Kalmaker to customise the tuning information, adjusting the fuel/air, timing and many other settings to get the most from your 6.

Does this process of computer replacement lose all the standard type settings that Holden worked so hard to develop - no, the Kalmaker software uses factory parameters and maintain the essentials for a road car, such as cold start etc. The process is easy with your vehicle being thoroughly prepared and analysed on the in house dynamometer to simulate most of the on road requirements without the risk or cost of inaccurate test driving.

Using the best of products we can optimise the power outputs of your six whilst improving the economy of this reliable motor.

Computer models are available for most models, so come in to see us and discuss your performance requirements.
