You need JB4 b type for n63tu. http://www.burgertuning.com/N63_JB4_upgrades.html

I believe this is the right link: http://www.burgertuning.com/N63_Jb_B...nce_Tuner.html

The last option on that page specifically says "N63tu Stage1 - For 2013+ 650, 2014+ 550 and 2014+ X5 50i models"

Do these void the BMW factory warranty? Is there any way the dealer can tell this unit was in the car if you pull it out before bringing in for service?

No works just fine, if you are worried about warranty just pull it out before taking the car to service, takes about 2-3 minutes
