Ram 2500

RAM 2500 6.7L Cummins — Performance Tuning

Our RAM 2500 tune isn't a single fixed file. It gives you multiple power levels built into the vehicle, selectable on the fly from the driver's seat — no laptop, no return visit to the workshop, no compromise between a towing setup and a power setup. You choose the map to suit what the truck is doing that day.

Depending on model year, the package includes four or five maps:

• Map 1 — Stock. The factory calibration, unchanged.
• Map 2 — Heavy towing. 258 rwkW. More power and torque than standard, calibrated for sustained load.
• Map 3 — Light towing. 273 rwkW. A step up for lighter loads and general towing duties.
• Map 4 — Power. 302 rwkW. The full performance map for unloaded driving.
• Map 5 — Late model vehicles only. A second performance map available on later model years.

Switching between maps takes seconds and happens in the vehicle. Hitch up a van in the morning and drop back to a towing map; unhitch in the afternoon and step up. The truck adapts to the job instead of the other way around.

All maps retain factory drivability and shift behaviour. Nothing about how you drive the vehicle changes.

Fitting and pricing

We fit and verify the tune in-house. Call the team to discuss your model year, the maps available for it, and pricing.

Please note

• Before and after figures are engine figures. They are calculated by applying the percentage gain achieved on our dyno to the manufacturer’s quoted power and torque, and are based on vehicles running standard wheels and tyres. They are provided as a guide only.
• Results vary between vehicles depending on kilometres, engine condition, modifications fitted, and wheel and tyre size. The before and after dyno print-outs supplied with each tune show figures measured at the wheels, which will be lower than engine figures. Larger or heavier wheels and tyres will reduce measured figures further.
• Vehicles must be in good mechanical condition prior to tuning. Increases in power on high-kilometre engines are assessed case by case.
• Additional parts and labour may be required where worn or faulty components are identified, and these will be quoted before any work proceeds.
• Prices are subject to change without notice. Images are for illustration purposes only.
