Hey,

We have this company in Sweden called "BSR"
They have really good reviews and offer some warranty as well.

Stage 1
BMW 540i 340hp 2017-2019
+ 60hp + 131nm
Total 402hp & 584nm

BMW 540i 360hp 2017-2019 (M Performance)
+ 41hp + 81nm
Total 402hp & 584nm

No box tuning, so you have to visit them again if you want to roll back to OEM
~€600

Stage 3
BMW 540i 340hp 2017-2019
+ 95hp + 168nm
Total 437hp & 621nm

BMW 540i 360hp 2017-2019 (M Performance)
+ 76hp + 118nm
Total 437hp & 621nm
Same, no box. + Front pipe after the manifold is replaced.
~€1600


Has anyone done anything similar to their 540i yet?
Both stages sounds very tempting

I have the M-performance kit already
