    Hey, I was reading one of your posts when you were having trouble with your car and thought it might be the O2 sensor. The symptoms you described is EXACTLY what has been happening to me. I was wondering if you ever found out what the problem was? Here is what you said, same thing that is happening to me:


    Idle seems to be ok, but it seems like at low rpm there is some rough patches between 2-3k only under load especially noticeable in the upper gears (3rd, 4th, 5th). WOT shows no change.

    Well I went to the dyno, and even though my car could build 21lbs of boost and hold it till 4500 rpm, after that it would drop to between 13-16lbs, the car still managed to put down 327 awhp and 351 foot pounds of torque.
