I am new this forum and this is my post but I had to ask for the most experience. The other day I had encounter a new Mustang Saleen which appears to be stock and from my knowledge most people I seen or know with those cars tend to keep them stock unless they got a lot of $$$. But anyways we were on the highway on a long strip four lane bridge. I see him tailing me and I waited to see if he was going to try to run. So I waited and used the tiptronic shifter put it in third to anticipate seeing if he was going to go. He was then next to me and all of the sudden he punched and wow he jumped like almost a car in a half to two cars. I kept using the shifter but then I shift until it was in normal drive when I did that I noticed I started to seriously gain some lengths on the Saleen and immediately caught to the back of his bumper that is when he slowed down and it seems like he didn't want to race anymore. So I want to know is the shifter actually better and does it move as quick as in normal drive and how fast are the 05-07 Mustang Saleens because his car was pretty quick?
