Moin Moin, have to make my 850 R a little faster. I’m looking for a proper tuning. I decided for the following components: – Chip Tuning – Downpipe with Kat – Sports exhaust – Sports air filter The brake system is already made and the chassis I left original except for a dome truss. I stepped on the tuners MR Sweden and BSR, which offer both complete packages. Does anyone have experience with these? The 330 PS packages are priced around 500,- EUR apart. Can it be that it is even the same software? The Downpipe with Kat should not actually be a witchcraft. Does anyone have an address where to make them?
