I really thought i could get a 8.5 with wider and better tires. I guess ill drive them a few more hundred miles and go back when i install my pulley. Maybe in oct or so. I was only expecting better times because i thought i could get my sixty foot down(figured 1.9) and i thought the car would now def be able to shift at redline. Everyone has mentioned to leave on "D". When i do it manualy it holds it a bit longer to about 5800-5900, instead of 5700 on "D".
