where did my performance go ??

Hi,

I thought to this day that I with my S8 incl. Chip from MTM is well motorized. A better one was taught today, but can't say exactly whether it was an S8. Was definitely a young boy, think after 2000. Had that Audi behind me today on the way home. When I overtook another car, he stuck to my tail. At my next overtaking I reached fully pure, second, third and fourth gear but without visible success. I let him overtake, but could not see anything from behind that points to an S. Now the thing went on in reverse wise. He's going to overtake me, and I'm going after him. Could not unlock the distance remained the same. When I arrived in Remels, I drove at our Audi partner Pollmann and Reuter in the parking lot. He didn't follow me (had overtaken him in the bend). I'd like to know what he's got under the hood. Was a Black A8/S8 New model, and also equipped with Audi 20". His license plate was AUR-FF and a two-story number. He went further towards Westerstede, wanted to play the game on the highway, unfortunately did not have the time. But would have liked to know how it would have gone on on the highway with the forces to measure !!!
