Hello all, I'm in the process of improving my mk4 golf. I'm looking to push 300bhp on my AUM 1.8t. I'm very new to this stuff and have heard people upgrade their throttle bodies for better flow. I was wondering what options do I have for my goals? I've heard the r32 throttle body is a good option over standard. If I fit that would i need an adapter? Also, would the car need to be mapped straight away or would it get away with driving with it until I get it mapped? Thanks in advance Jason
