Keep in mind that dyno numbers are subjective and can vary wildly. Find a nice, optimistic dyno and 400whp may be possible but that doesn't mean it's any faster than a dyno reading 380whp.
Hey 380whp is perfect. My n54 xi wasn't putting that much down!

Yeah if i end up wanting more power then i'll look into turbo upgrades

I haven't heard many people complaining about reliability with the N55 so thats a good thing

It'll be stock for a while so I'll have to get used to stock power

I don't mean to get off topic though. OP, the N55 is definitely a great platform! Plenty of power, and hopefully there will be some more aftermarket turbo options soon for those of us hungry for more .
From what i've read it doesn't sound bad at all! As you said, aftermarket turbos are always a solution.

I haven't read up on the new F30s turbos but I just figured they could be tuned as the e9x series' turbos were
