And one thing more. There 2 types of tuning boxes for N47 on F30:
1) Box that connect to Common Rail (JBD, Racechip and other).
2) Box that connect to Injectors (AC Schitzer, Hartge, Kelleners, Steinbauer).
You have to know that AC Schitzer, Hartge, Kelleners and Steinbauer are selling THE SAME tune programm!!! But prices are different.
Just check the manuals:
