Xtremetuning works mainly as the technical partner behind automotive workshops and tuning dealers. Alongside that, we take on selected retail and specialist projects for vehicle owners, including unusual tuning jobs. Tell us about your vehicle and what you want to achieve, and we will send you a tuning summary for it.
What we can help with
- Onsite and offsite ECU tuning
- Increasing engine performance
- EGR, DPF and AdBlue enquiries – options assessed for your vehicle and application
- Diagnostics
Applications we work with include:
- Passenger vehicles: utes, cars, SUVs and buses
- Transport: trucks
- Construction and agricultural machinery: excavators, cranes, tractors, combines and more
- Motorbikes: road and dual-purpose bikes
- Marine: four-stroke inboards and outboards, and jet skis
What can be tuned depends on the vehicle variant and model year, the ECU hardware and software, and the other technologies involved, so we look at each vehicle individually.
