[Dheeth-G80]

Car is 2017 540i

I had a FBO N55 with Bm3 custom tune so I researched and found lots of stuff.

For my B58, what parts do I exactly need to go FBO? I just got it yesterday and my eventual goal is Stage 2 custom tune like my F30.

I know for stage 2 I need Charge pipe and downpipe, do I also need the heat exchanger? if so what would you recommend and has anyone done any of this yet? How about a DV+? Spark plugs?

I am asking this because I did hear lot of the stuff on this car is well made over our older cars so tryna find that out.

Another question btw, I paid extra for the bmw unlimited mile extended warranty so would they really flag my car if some oil leaks happen and stuff like that? The usual engine wear and tare I mean for B58

On my F30 I had route66 and took it in couple times and no issues, they knew its tuned but my SA is pretty cool
