Don't try to chirp your tires if the car won't do it on it's own or you'll be wearing out trans parts. Plus, if you do get them to chirp and that's it, your friends will be making more fun of you for even trying and only getting the little chirp.
If you want more performance, get a chip to change your ATX shift points, open up the exhaust and intake a little bit. Should help get you more kills (which aren't to be posted on CEG BTW

).
