Tuning – Increase PS

Hello, I’m completely new to this area, so I have to ask such a stupid question. Where can I look around or ask myself, with which we can bring up the 3x BL from 151hp to say about 180hp. Is this possible without investing another 10,000€? What can we do for about 2000€? What does a tuning chip actually do? Can I use it to shorten the switching operations? I own (still) an old Ford Puma – it has very fast switching operations, and that makes it possible to do a fairly good job. fast and short precise switching. This is not the case with the 3 Series. Can you change it? Enhance it? Thank you very much. Kosta
