I have a 2018 F90 M5 and I am amazed at the performance the stock M5 provides, and The comfort … truly a velvet hammer. It goes, I mean it really goes … stupid quick, but always in control. The CC brakes stop like a brick wall.
I recently read about the Dinan Stage I tune that has been developed for it. Has anyone installed this tune, and what was your experience with it. Is the increased performance noticeable - any times you can share? Have you had any reliability issues since the install?
