I run the JB4 box (BMS) on my M6 at +4 and have never had an issue. DINAN and JB4/BMS will make around the same power. You will hear arguments from both sides about which is better -- it's same shit if you ask me. Only difference is DINAN offers "their" warranty if the tune harms the engine vs. BMW offering nothing. You also pay $3,000+ vs. $450 so pick your poison. FWIW I have never heard of the BMW/JB4 box causing any issues to anyone's car.
I am waiting to see some numbers on the AMS tune that was released a little while ago. If there is more power there vs. the JB4 I might switch over but for right now the JB4 makes a ton of power and you can adjust it as needed, data log, it will control meth, etc, etc.
