Technical Centres.
Some people ask why we only supply OEM+ through dealers, rather than choosing a 'flash at home' option. It's because to properly access a car's ECU programming is a complex and technical task.
We believe in doing the job correctly, especially for such a technical upgrade. We've chosen our global network of OEM+ Technical Centres to verify the health of your car prior to flashing, to ensure that the programming has been correctly installed and finally to verify the successful performance after install. And, to be there for you should you have any concerns post-purchase.
After all, aren't some jobs are best left to the experts?
Serious software.
Serious hardware.
Every one of our calibrations has been developed right alongside our world-renowned range of Performance Parts hardware.
Reassuring to know that you can select a full suite of hardware and software, with both aspects developed in tandem with the other, to be sure that you're getting the most out of your car's capabilities.
