Hello people On Thursday I left my Volvo S 80 D5 bj. 2007 with 185 Ps and 400 Nm from BSR “chips”. Directly it is not a chip but a control unit that is connected somewhere under the engine cover, takes over the original data of the ECU and then optimizes the engine by a learning phase. According to BSR I should then have between 225 Ps and 230 Ps and come from 400 Nm to 450 Nm The product:www.bsr-tuning.de/produkte/t953/ The product will only be active after connection. If you accelerate 3 times from 0 km/h to 50 km/h and after that you accelerate 3 times from 0 km/h to 100 km/h. From then on you do not feel an extra power immediately the full power. The system learns constantly and you feel the extra power more and more. That means, a little patience needs recommend I can speed you, more times from 1 – 3 gear, up to the limiter.To limiter: The limiter is now on 5000 tours and not as before at 45000. I was then h The result is VERY positive! I now have 235 Ps and exactly 500 Nm. I paid 1200 Fr. incl. installation. And 235 Km/h were in it! I can recommend this product to you! Here is the controller from BSR “hidden” Gruss Jimmy
