Living in Germany working for the Army I drive 106 Miles one way to work with about 90 of them on the Auto bond. I drive my RT at average speed of around 80 to 90 MPH. I have been up to 140 MPH, which is as fast as the factory governor will let you go in a RT and handling was still as if I was at 80. I have driven many of the European BMW, Mercedes and Audi’s and you can only get this type of handling with the cars that start at $80,000. Lear4406 how did you get yours to 150 MPH, have you found a chip that will bypass the governor? I know the car can do it without a problem, I shift into 5th gear at 140.
