I had the Giac stage 2 flash done today at pfaff and it is incredible. Still very smooth but so much more power. this paired with my other mods is amazing, now i want meth.
I am going to put it on the rollers saturday for the meet so looking forward to seeing what it puts down. I don't have a baseline so i will go by what mike has done as most of the n54's seem to be very consistent.

Am thinking along the same lines. How long did it take? Any other mods necessary for Stage 2? Worried about warranty?

I see as of March, all E90 335i's will have the N55 engine. Glad I got mine just in time for the N54 (Dec 09 delivery of a MY2010) - washed it for the first time today... (aside from touchless crappy washes).

It took about a half an hour to and hour. If the stars align that's all it should take but be forewarned that they may encounter problems with the file, i couldnt say and you won't know until it begins.

You need an intercooler, fully catless but on dp's will suffice and it would be in your best interest to get upgraded diverter valves or a blow off valve.
I'm not to concerned about warranty they can see the flash but everything else is noticeable. i never really considered it, i act on impulses.
