Berger JB4 Piggyback System

Looks like Berger tuning came out with a piggyback system recently. Has anyone tried it out?

Going to revive this post. Buddy of mine just got this system. Was curious if anyone on here has played with it. Currently have the Eurocharged Stage 2. Really want the ability to record data, and possibly play with boost in low gears. Anyone have any insight? Thanks!

I've used the JB4 on my prior BMW 535 I and my current C63. It is excellent and works very well, user friendly, and has features like logging, boost by gear, safety controls for AFR, etc. and multiple built-in maps, that other tuning solutions cannot match. Also very easy to switch between ethanol and pump maps, Which is convenient and avoids headaches if I am not near the ethanol station.

PS - it is "Burger" not berger.
