Texas Jim Posted July 27, 2006 Report Share Posted July 27, 2006 This is probably a stupid question. I have a '06 DTS Performance Edition with "H" rated tires. What speed is it limited to? I have ran it up to almost 130 a couple of times, but ran out of room to see where it kicked in at. It does that SO EASY........ Link to comment Share on other sites More sharing options...
chazglenn3 Posted July 27, 2006 Report Share Posted July 27, 2006 I believe that "H" rated tires are rated for 130MPH...so you were right there. The limiter on my '99 STS with "H" tires is at 130. Charles Charles Link to comment Share on other sites More sharing options...
The Fred Posted July 27, 2006 Report Share Posted July 27, 2006 Someone on here tells me that Concours are (is) limited to 130 and I'm fairly sure they come with H tires MerryChristmas Be a Capitalist or work for one.

Texas Jim Posted July 27, 2006 Author Report Share Posted July 27, 2006 Thanks guys. You have again answered my question. Reckon I don't really NEED to go over 130 anyway. Link to comment Share on other sites More sharing options...
Cadillac Jim Posted July 29, 2006 Report Share Posted July 29, 2006 I have Z rated tires on my 1997 Eldorado Touring Coupe and I don't feel any strong urge to have the governor taken off. If I ever take that car to Germany or some other improbable circumstande, I will have it done. From posts here, they way that the dealer does that is to reprogram the PCM using the VIN of another car that comes with Z rated tires. I'm not sure that I like that. I thought that they just reset a flag or some such. I've had mine up to 125 and it was right in the power band for 4th gear and felt really strong. It wanted to go. I do point out that the FSM says that the governor works by shutting down the fuel injectors. I'm not sure I want that invoked on my engine, although I'm sure that they know exactly what they are doing. -- Click Here for CaddyInfo page on "How To" Read Your OBD Codes-- Click Here for my personal page to download my OBD code list as an Excel file, plus other Cadillac data -- See my CaddyInfo car blogs: 2011 CTS-V, 1997 ETC Yes, I was Jims_97_ETC before I changed cars.

TDK Posted July 30, 2006 Report Share Posted July 30, 2006 Folks, My '94 Deville Concours runs OK in the mid to high 120's for any number of miles, so I would guess its limited to 130. However, I fond it disconcerting to run that hard though for 20-30 rail-straight miles at a stretch - alongside ranch fencing, trees, poles, etc on narrow 2-lane roads. The term "tunnel vision" becomes quite relevant. You tend to worry too much about being focusing tightly - yet become bored, distracted after while and drift out of a tight line. Kinda like hynotizing that ole chicken with a line on the floor... Regarding the fuel limiter. My 99 GMC would get hit hard at around 97 and loose several mph only to creep back up. When we had a hard run of about 2-hours flat out, it took a bit to stay just under the limiter (I forgot to try the cruise control at 96...). By comparison, my 2006 Chevy company pickup with a couple hundred miles on it - is undetectable engaging its limiter at 97. Regards, Add power to leave problems behind. Most braking is just - poor planning. Link to comment Share on other sites More sharing options...
