Ahh, they use the factory tune for a starting point - they take your program, patch it, and reload it. I suspect it must have a key that and/or some kind of cipher that authorizes the program, that's tested during startup, interesting stuff.

The ease of install/uninstall is very compelling, even with the cheaper JB pricing and the extra features.

Yeah, factory FI is always slick for adding some HP. Tune, a little exhaust work, so many FI cars can pick up 75-100+ HP. It's one of the things that makes the N5x powered BMWs so interesting!
