You can run up to map 3 but it will be like sh*tty. Log Map 1 through 3 and post it on the forums (N54). They will push some revisions on your JB4. If you want to take it further you can...
Yeah I can expand on this issue. It DOES get choppy power delievery when WOT. I don't know the exact fix for this. Even with TSC off and sport mode. Other than that its plenty of fast.

Like said above, find someone near by with an ECUTek Dongle and take it with you when you look at the car. Chances are its unlocked and you will be good to go for a tune. That is what I did with my LE.
Just have money on the side if it is locked and needs to be unlocked
