I saw on the turbo idea thread that 2K1YellowMP3 had his car dynoed and they said it was running too rich. If you will notice when your car hasn't been washed in about 2 weeks or so, that there is a lot of soot build up on the muffler tip. I have'nt washed my car b/c we are expecting so much rain, otherwise I'm psycho about washing it. Any ways,...I was wonderng if anyone else noticed this.
