The throttle response is also more linear and direct than it used to be. The MPG has increased slightly too, but this was not a deal breaker if it didn't.

All I can say is that if this is something you are contemplating, I can say with 100% certainty that I made the right decision. I also want to give a big shout-out to Logan and Hal at Dynosty for their care and concern for me and my Z during this tune. They are professional, courteous and they know WTF they are doing. This is by far the best $$$ that I have spent on the Z to date.
