I come from the Subaru world, where there are a bunch of off the shelf products that will show gains, but to get the most out of your car, its necessary to get either dyno tuned or road tuned. Is that because of a limitation of Subaru's ECU? Or would the N54 benefit from getting custom tuned if it is available?

As far as I know right now, none of the tuning companies offer custom tuning. (Please, anyone correct me if Im wrong on that). I have no doubt that it would be possible and beneficial to do so. If you have added an intake/exhaust/intercooler, a custom tune could better take advantage of those things.
Also, I *think* all of the tuning companies use piggy back systems right now to hide what is really going on to the ECU. I know GIAC plans on releasing software and will probably be in the form of an ECU remapping (if the BMW ECU allows it). This still wont be a custom map, but there may be things in the ECU you can tweak to make it a bit more custom.
