what i've done with every ticket, no matter what it has been (including my DUI) is show up, and plead not guilty...they will then assign you a court date....show up early on your court date, and ask to speak to the prosecuting attorney (the officer should also be there, if he's not you already know you're good to go) tell the attorney your story, tell him anything you've done to fix your problem, or whatever...give a good reason, which includes just saying "i was feeling a little bored, and I just installed [insert performance part here] and wanted to see how well it worked. something like this should fly with him...
he will then dismiss you so he can confir with the officer, then he will call you back in and you can discuss the plea bargain.
i've taken every ticket i've ever gotten, no matter how guilty i was, and followed this method....everything's been reduced, or totally gotten rid of
