Hello,

has anyone done a custom tuning to the B48 252hp engine?
I own a 2018 530i with around 60k miles (100k km) and I’m tempted to do a custom tune by a local professional (including dyno measurements before and after etc).

He told me a safe rune would mean an increase in power of around 30hp and 100Nm in torque.

Do you think it’s worth it, or the risk would be higher than the gains?

Thanks a lot
