2000 Deville DTS here..
 

I took it to the track and she is running smoothly. However I am curious, is there an easy way to over ride the speed governor? I hit 111mph and the fuel gets cut off and I know it can push past this.

Thanks for any replies.

disappointing, eh? Good luck getting the computer re-programmed!!

Programming required. If It's a real DTS car should have bucket seats and console. VIN should start 1G6KF579 and top top speed will be over 112. GM's policy car will NOT excede speed rating of original/ built with tires, DTS did not come with S rated/ 112mph tires. If someone swapped PCM with base Deville it would explain it.
