The other day my neighbor and I just happened to be leaving the house at the same. He owns a '01 Audi s4 wagon with an exhaust, blow off valve and an APR race chip. I've driven the car and can say it's pretty fast, but it has Tiptronic (yech!!). Anyways, we made the same left turn onto an open two lane road and it was on. We started at about 25mph and were dead even all the way up to about 90mph at that point we cut it off. I was surprised since all I have is an mbc and axle back. Just wait until I get the uppipe and complete turbo back, I think it might be a different story. The car is pretty sweet with all the amenities I must say though.
