Hi, Just joined the group. Keen to enquire about tuning the F10 520i to have a map like the F10 528. I dont want to unnecessarily create another thread if this topic has been discussed at great lengths in this forum. If it has been discussed, much appreciate if there is a thread i can read up on. Meanwhile, i will browse through the forums on the topic. Thanks in advance for any leads. Cheers. Happy driving, stay safe!
