received my Sprint Booster a few days ago and today I installed it. Well I am shocked my car doesn't feel like my car anymore and I only had it in sport mode, I will try the race mode on a clear day without traffic. One thing I noticed is that I will not need the "rev matching" feature on the Z as when you downshift the RPM's remain high enough to make it shifting much easier. Not sure how to explain this, one thing is that I like my Z now more ....
Props to Sprint Booster, the best mod I've done and it's not snake oil fo sho
