I was pretty suprised when I saw the numbers to be honest. I think there was still room to improve in the ets. When I had the car put on a chassis dyno I saw the car pulled all the way to 5300 rpms. When I went to the track I left the car in drive where it automatically shifts at 5000 rpms. So who knows maybe there was another mph left in the old setup. But I am not looking back!
