as stated before the SVT/ST200 do not have speed limiters- but you may have a high load lean out condition effecting the motor- it is very common for that to happen at such speads and especially if they are sustained for a while- thats is why most tuners cars cant withstand an autobahn run- they blow pistons from a high load sustained drive. most have access to a drag track and on such are VERY impressive but any HW cruising past say 100 ish MPH and they run into a whole bag o problems. (notice how Most euro companies can do such tests and not DIE!- excluding of course RENNtech- as they have a marvelous ability to whenever they are mag tested to mysteriously poop.
