As delivered from Ford the V6 is limited to 113 MPH... You don't put a
"chip" in this car. You will need to buy a handheld tuner and reflash
the car. Most of these will either remove the limiter or allow you to
raid the limit. The car should easily be able to hit 120 MPH...

Besides making sure you have the properly rated tires, I would also be
leery of the stock drive shaft... they are pretty much junk... They
vibrate like crazy.... also I don't remember exactly when Ford
switched but the early drive shafts did NOT use C-clips to hold the u-
joints in... instead they were staked in... but eventually the stakes
would give way any the drive shafts would come apart... which is very
bad thing to happen at 120 MPH... luckily the ones I know of were all
on the dyno... but still caused a fair amount of damage...

Even if you drive shaft is clipped I would still recommend an after
market drive shaft if you plan on doing a lot of high speed
driving.... I couldn't keep a rear pinion seal in my car until i
replaced mine...
