Very happy with the chiptuning of my 2020 X6 G06 30D. I was concerned as my car is new (less than 5000km) and did not know if BR Performance was up to date software wise but they are! I’m very pleased with the outcome and while using Dragy I’m now 1 full sec faster from 0 to 100 km/h which is quite phenomenal. The engine was prior Stage 1 very nice but now it is pure pleasure. I strongly recommend BR-performance Netherlands and don’t go cheap cause I the end you get what you paid for.
