640i tuning and service

Hello My f13 640i 2011 has chiptuning and my question about it is what it looks like with the service. So warranty for motor damage etc is anyway gone. However, you still have up to 100k km “free” service (the hours) If I now snow by, I get the service still so free or does it not apply because of the tuning? Provided it is noticeable to you. Thrust circuit is disabled, so audible it is definitely. Please no tuning lane posts. My vehicle. Not yours. At the same time What are they going to say about this? Service they do either way, only question is if I get the hours for free. If not I want to save time and make the service directly in Germany, because cheaper. Thank you very much.
