Stock SVT rev limit is ~6750 at least the one that makes it fall on its face when you hit it is IIRC...not 5000. Here's a thought...what RPM does your car idle at ? If it's up around 1200...check you tach and I would guess somebody has been messing with the gauge needles...perhaps a indiglo gauge install? If you don't know what you are doing with these the speedo & tach can be way off when installed and will require recalibrating.
