As Mike said above, I'm running his stage II tune and catless downpipes. All mods are listed in my sig below.
My SA is aware of all of my mods but BMW NA is not. I'll be purchasing an extended warranty soon and if BMW agrees to it, then I'm pretty sure that there are no 'flags' - or more probably Mike's tune hides everything extremely well.
