No confirmation that the X5 will get COBB support, especially since the X6 had the N54 and doesn't get COBB support currently.
If you want a flash, you're better off contacting Eurocharged Performance, Active Autowerke, GIAC or Dinan (all have N55 tunes for the X6). Otherwise you can only buy the BMS Stage 1 N55 tune (Stage 2 does not support X5/X6 platform).
