When you buy a PPC tuning kit you have the choice to either buy your own PPC device or use a loaner (Basic) that you return. The advantage of buying your own PPC device is that you have the assurance that you can always reset to the original settings, and that you will always be updated with the latest software. If your service station sets your car back to the original settings, you can simply load the tuning kit again. Those of you who already own a PPC 3 device can transfer it over to another car, and only pay for the software of the new tuning kit. This is a very economical option if you, for example, sell your car and want your new car tuned. You make the transfer yourself, quickly and easily, directly on our homepage via your own login site. As soon as the transfer is complete, the support for your old car is canceled.
If there is a new car warranty left on your car, then a warranty is included in your purchase of a tuning kit from us. This warranty can be extended up to a maximum of 4 years or 12000 miles. Read more about Machine Warranty here
The car inspection (Bilprovningen) has no means of checking to see if the car is tuned by BSR or original.
BSR has extensive expertise and experience in working with in torque and horsepower, so there is no risk of negatively effecting either engine durability, or of straining the transmission and clutch. It’s also crucial that the torque is reduced in critical moments, for example when switching gears and that’s why BSR tuning kits have appropriate upwards limits on each of the gears/steps. Our software is uniquely adated for each drivetrain, 2WD, 4WD, manual, automatic DSG, etc.
By only utilizing the max effect when you really need it, and taking advantage of the improved torque - ie a form of "unconscious eco-driving" - you can reduce the average fuel consumption by a few percent with BSR tuning, compared to the original.
Everything done on your car is logged and is traceable but, no, is normally not visible unless you specifically looking for it. We do not however recommend that you conceal the fact that your car has been tuned from your service workshop.

When you want to upgrade your software to Stage 1+ you go to your PPC-site and if you want to upgrade to Stage 3/4 you write in our support .

We will then send you a link for payment via e-mail and when it is paid we change it to the software of your choice.
