I was just reading a preview/review article on the 2005 Mustangs on www.musclemustangsfastfords.com, and one of the things they write is this:

Ford refused our request to get a car for instrumented drag testing until later in the year, but we'll tell you that this car feels stout. Torque is better than we expected (no doubt bolstered by the 3.38 First gear and 3.55 rear cog), and the engine pulls more like a four-valve Mod motor to redline than the old two-valve 4.6. Our best guess is that with a power-to-weight ratio similar to the '03-04 Mach 1, good racers should be able to get the new GT into the mid- to low-13s at over 103 mph at the strip in bone-stock trim. If it can accomplish this, it would be the quickest Mustang GT ever. Even if it misses by a tenth or two, it would still probably qualify for title. Top speed is computer-limited to 145 mph.

If the top speed is computer limited, would a Tuner be able to outright override that, or at least adjust it higher? Also, would it be safe to say, that if Ford set the top speed to be artificially limited, that it actually has a higher top speed iof 145mph?

 

A tune from sct or diablo or anyone else can remove the limiter or raise so high it ownt matter. And i am more then sure they can go faster then 145mph.
