:hmm: Does anyone know how to view, or change, the setting that was used for limiting top speed on a 2000 DeVille DHS N* with 275 HP? I have "H" rated performance tires, same as the OEM tires were when originally delivered. They are rated to 150+ MPH. I would like to know before ever attempting to reach that limit on the highway. Not that I intend to do that any time soon.
But one never knows :lildevil:

First, H rated tires are only rated for 130mph, not 150. Second, the only fewasable way to remove the governor is to find a shop that can reprogram your PCM with the info from a Z-rated DTS, which probably won't even work. It would also be quite expensive.

Not likely you'll find anyone willing to take on that liabilty in todays litigious society. The trial lawyers are salivating just reading this post.
