The M3/4 will be terrific.

For those of you thinking that someone will quickly come out with a tune...lol.

The dual Bosch ECU's have proved impossible to fully crack. Which is why the M5/M6s have disappeared from our SoCal Airstrip roll-on events. With a tune or downpipes, M5/6 owners are getting limps at various speeds as the BMW engineers have hidden code in various places which so far have been undetectable.

Increases in torque over specified parameters over a certain duration will trigger limp. I have a buddy with a $6K tune and another buddy with $3K downpipes (no tune) and it happens to them at around 130mph.

The new M3/4 will have the same ECU and likely with even more sophisticated stop limit protocol and already 18.1psi of boost from the turbos. The best tuners/hackers will need years before a viable tuning product is even available.
