OBD2 port tune for N55
Hey guys, i was wondering if anyone here knows if you can and where to get a tune such as COBB for my X6 35i N55 engine... Every where i look they only have piggy back tunes or full on bench tune, where they have to take my ecu to flash. I'm all about convnience so as of right now im running the JB+ on my x6 but i want one such as COBB, any suggestions or thoughts?
