Hi All, I have a 2016 F10 520i. Was considering remapping the ECU. Understand the same gen 528i and 520i share the same engine specs and internals and that the 520i is a detuned version. But i stand corrected with the experts. Am not looking to boost the performance to some crazy numbers. Was hoping to get a similar map like the 528i or equivalent. Does anyone have information to share what are the possibilities and where are the recommended places to do this? thanks in advance.
