I've seen posts from a few people using it. Mostly positive, and good increase in performance on the Hurricanes.

I used to use a JB3 on a BMW 535XI...it was pretty amazing and fairly easy to use. The new versions with phone app gotta be better I'd think.

I've used a JB4 on my 09 BMW 535i (N54 inline 6 cylinder with twin turbo) and it worked pretty well. I haven't used it on any other vehicle though.
