Whether you’re working with petrol or diesel engines, or targeting a Stage 1 or Stage 2 setup, our configurator helps you quickly find the ideal file for your Western Star project. All files are fully compatible with major tools such as Autotuner, Kess, and Ktag, and are available 24/7 through our intuitive platform.
We supply custom-made ECU tuning files for petrol and diesel engines. We do this in a reliable, affordable, effective and efficient way. Our tuning files are extensively tested to ensure that all our files are provided with the best quality and security. There’s a reason why 95% of our tuning files are dyno-tested on our own dynamometer. With our chiptuning files, we provide the answer to the increasing need for optimization of engine technology. Our chiptuning files provide improved power and more economical fuel consumption for all petrol and diesel engines. This guarantees better performances, more torque at lower speed and most importantly: more driving pleasure!
