[twin turbo]

I have contacted Burger Motorsports about the JB+ and JB3 piggyback as possible tuning options. I owned a 2007 335i with the Dinan flash. It made a huge difference in the cars performance with no ill effects. It doesn't look like Dinan offers a flash for this car yet. I am concerned about adding just any tune to this car because of the adjustable suspension/throttle/steering option in this car. Thanks for your input.
