Funny....I also just got a 335i (I'm in love!!!) and I was just looking for the same thing myself.
My Stupid-Wild-Assed-Guess, based on what I'm seeing in various charts showing various different bolt-ons, fuel types, and tunes, is about 355-360whp on Map5, DCI, and 93 oct.
Add a set of downpipes and an aftermarket FMIC, and you approach 390whp or so.
Opinions from more experienced and knowledgeable folks?
