Ive been told that my new '03 V6 ECU will shut down fuel delivery at 118mph!!!! Anyone know if thats true, and if so, how or who can be trusted to modify the settings...Thanks....DD

Well the 2000 has fuel cutoff set at 128MPH. I don't know about the 2003. As far as modifying the ECU to bypass it, I don't know that I'd trust anyone to do that. I'm not sure if the JET Chip ($400) provides differnet mapping of the cutoff or not. If you do it, make sure you have Z rated tires, which is why the fuel cutoff is there to begin with.
