35iS overboost?
"The BMW E89 Z4 35is comes exclusively with a computer-controlled overboost function. The boost function activates after every gear change with full throttle, and lasts for 7 seconds between 1500 and 4500rpm. During that time frame, the car will have reached 500Nm of torque for 1-2 seconds, an increase of 50Nm (37lb-ft) over the 450Nm (332lb-ft) without overboost. The full 500Nm comes in 3rd-7th gear only."
So, when you floor it, for 2 of the 7 seconds of overboost in 3rd-7th gear, it produces 500Nm?

You temporarily get higher boost/power, as mentioned already-get it remapped & have even more

I think it means it sounds loud and goes quick?
