My current setup on a 2018 540i M sport
High Flow catted downpipe
M performance muffler
Resonator delete
BM3 stage 2 at 93 octane
XHP stage 2
I have a B58TU HPFP sitting in my garage waiting to install but I was told it doesn't do much if you don't plan on switching your fuel mix. 93 octane is just simpler in my opinion just dunno if it's worth going up to stage 2+ and stage 3 XHP

I am stage 2+ and certainly feel the difference over stage 2. I am also stage 3 with xhp
Do you currently have loud upshift farts?
