Do a search. The bottom line is that the speed limiter was set at the factory based on the tires that were originally ordered on the car. The car without a speed limiter is well capable of 150, at least the DTS version is. NO you can't get them to change it.

Like the rest of us you have now learned to read the door sticker BEFORE buying the car.

As I recall, there is a chip for '93-95 model years that disables the speed governor .
112 is not to be sneezed at all just imagine you don't have HT4100 lol

I wish someone could disable it, but it'll never happen. Nobody wants to hack the N*.

You have obviously NOT been keeping up my friend.

He speaks the truth.

Mikeman, Change your vehicle profile so the model and year shows up in your header. It will make diagnosis and recommendation easier if we know whether your car is a 1935 Phaeton or 2003 DTS. (Yours sounds like a S-rated DHS - look at the tire rating sticker on the driver's door jamb. The rating will follow the front and rear tire numbers.)

At the same time??
That statement is not correct. I don't think I can do it on a Metro. I can do it on all Northstars and possibly all Cadillacs. In theory If I can find a Z or W rated tire 03 CTS I could copy and paste that portion into the program.

lol
mines limited AT 130 for now lol and my ETC isnt rated period
your 00 with W is limited at 150 technically.


and the answer, the fastest Deville is a 97-99 Deville Concourse, they came from the factory with H rated tires (no w or z was available) limited at 130, your base Deville and Deville Concourse (95-96) came with S tires (no other speed rated tires available) limited at 112.
