I know someone who had one on a 350Z and they said it was very good.However, that was about 3 years ago and I think things have moved on and there alternatives now. I have the UpRev tune on my 370Z and I have 5 different throttle maps to choose from. I think Abbey Motorsport (who mapped my car) are looking at tuning other Nissan's including the Juke. The thing is though, UpRev gives you a lot more than just a better throttle response. You also get more torque and better economy - but not at the same time!!
