I actually asked a similar question the first day I bought my Z. But every time I took a small break from driving it, it seemed to get better. The only problem is 1st to 2nd. There is so much torque compared to my rsx that I have not gotten used to it yet. And right around 3.5k rpms be careful speeding up to pass someone if your going to compare the Z to an SI because the Z seems to want to play bumper cars with the car infront of it
