R56 NM ECU Flash
NM ECU Flash
Being that I live around 2 hours away from NM, I was considering taking a day off to get their ECU flash on my 09 r56 once I get my FMIC. Before I commit though, I was just curious about any pros/cons/better options. Money isn't too much of a concern since I wouldn't mind simply saving up a bit more. I'm more concerned with reliability/results considering I do daily my car as a college student.
