I like the Cobb, but the JB4 seems to have it beat for features.
Cobb (experience on n54 with my 335 and now 1m) is much smoother than piggybacks and is a superior and safer form of tuning.

The in dash gauge features are gimmicky IMO. Get a p3 guage if you really want real time data.

Uninstalled cobb is not detectable.
