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.

bumping to see if anyone with a Hurricane has purchased this?
