With the ECU Tune, we also recommend having your Transmission Tuned. This can be added into the package when your are planning your performance upgrades.

We also offer Switch On The Fly (SOTF) tuning for the Duramax, this involves supplying and fitting a 5 position switch which allows you to select from stock power level to extreme, allowing you to choose the appropriate level for the conditions.

We stock and sell full 4 inch “Race” Turbo Back Exhaust Systems which are made in the USA. Our tuning solutions have been learnt from the best in the business – the United States.

Our Chevrolet 6.6LML Duramax ECU Remapping also improves drive-ability and economy. The process requires the vehicle to be at our workshop for just the day. Our specialist tuners set the vehicle up on our All Wheel Dyno for a baseline dyno run. We then through our iterative tuning process, tune and revise the tune until it perfectly suits your car and its modifications. All this is done to a safe industry standard ensuring maximum reliability and longevity.

    ⭐⭐⭐⭐⭐ Excellent product upgrade to my 2015 Denali. Now a totally different truck, heaps more power/torque and improved smoother transmission response with the TCM Tuning. The increase in torque allows the truck to remain in top gear over most inclines while towing, resulting in fuel savings.
    Fuel economy has been improved, 8-9 litres/100k city and 15.7-16.0 litres/100k country towing 3.5 tonne van at 100kph.
    Extremely satisfied with the results.
