2) Whistling sound when cruising around 1.5 to 2.5k rpm.
3) Sudden jerk when cruising.
4) Weird idling rpm.
5) Engine died when caught in slow traffic.

Anyone experience all these? Any other tunes to recommend. I really feel like giving up on JB4.

Currently I am on Map 0 and I dont have all these issues except Point No. 4.
There are no known issues with the N55 Stage2. Your first step should be to contact BMS for support, they can probably help you find your problem.
