New releases


Testdrivers comment :

Solid German car that runs nicely on the road. It is obviously made for long comfortable trips. The car is big and heavy and the engine might be a bit small. When the car is tuned with BSR stage 1 it gets the additional power that should have been there from the start, and the overall feeling of the car is improved.

We have reduced the price on hundreds of tuning kits that, through the years, has contributed to the success of BSR. In our solid collection, based on over 25 years of engine optimization development, we have made a wide selection of popular and successful tuning kits that contributed to BSR´s development in different ways. To give something back to our customers, who has contributed to the success, we cut of a big slice of the price tag on these. How about €290 for a tuning kit on a Volvo V70 2,4T 200hk (2002-2003) or €248 for tuning tuning to a Audi A3 1,8T (2002-2004)? Visit the site and check if the tuning kit for your own, or your friends, car has got its price reduced. 


Its been a while since the big scandal that revealed a huge and systematic fraud with emission tests on Volkswagen´s diesel cars. A lot have happend since then and the developement by VAG (Volkswagen, Audi, Skoda & Seat) to get everything straight is still ongoing and that is why they are releasing a lot of software updates at the moment. However, to get this right and keep the driving experience as it was through software changes has turned out to be close to impossible and a lot of VW´s customers are very disappointed. The perception is that the new softwares has a negative impact on the performance and driving experience. This is why we recommend car owners that are affected to wait with any updates until VAG releases a software which doesn´t have a negative impact on the cars driving experience.

If you want more information we recommend you to stay updated via trusted online forums and other communication chanels where consumers evaluate released software updates. Swedish magazine Teknikens Värld has investigated and written a lot about this:


BSR´s software are always based on the software version that the car had when it was tuned and are not downgraded to older versions. 

The webshop expands every day when it comes to spare parts and tuning as well as our own merchandise. Lately we have added Sunglasses, a rechargeable air pump and stickers to our range. Check them out:

We did it! After a long period of hard work our engineers managed to tune Volvos V90 D5 with results we did not dare to hope for. The measurements and the result compilation is in progress but official values are not set just yet. However, there is no doubt that this breakthrough will open up for development of tuning kits for all models in the 90 series. Keep yourself updated on the progress by following BSR on Facebook and Instagram. 

Yeeha! 10000 likes on facebook and 1100 followers on instagram means cake time at the head office! Thank you all! Now we head with full throttle towards 100000!
