The fact is, when you are rolling at a very slow pace or even at idle, and floor it, the engine doesn't even begin to really rev until 2-3 seconds later, and that is with the throttle all the way down. It just doesn't wind up like it did in my 350Z, and anyone who previously owned one will know this.
