first of all, if you got a radar detector then the cops will easily know that you've got it because cops in some cities got the "radar detector" detector. so whether you going 200mph or 10mph, they know you got it. second, wanna a faster "auto" car? shifting manualy could help little bit, why dont you get a turbo or nos? try search the net.... hotshot.com for example. i know couple "auto" Ga16det in my town who make the sr20's and other ricers bow everytime they pass by. dont listen to anyone who says that your car is slow. you can kiss some serious ass if you know what to do next.
