Someone in my family is a major car buff. He told me about a friend of his who had a tricked out camero, so he brought it into the place he worked(he was at a chevy dealer at the time) and remapped the ECU with a police program or whatever you'd like to call it. it took 1/2 second off his 1/4 mile. my question is, is it at all possible with proteges, thusly including MP3s. I know you can't put in a new chip like on a Jetta 1.8T, but I'm just wondering....
