I have used V-techs powerbox in my 2005 X3 3.0DA. It was ok, but a bit edgy when taking more power out from it.
Couple months ago took the box away, and updated the engine software. Now iPhone app dynolicious reports 6.12s 0-100kmh. (before 7.4s). And 289 hp.
Fuel economy didnt change. Maybe a bit less when driving normally.
I recommend
