Why has my STi II got a serious flat spot around 5500-6000rpm? http://bbs.22b.com/ubb/eek.gif This is especially obvious in forth gear, the car literally slows acceleration and then goes again.

The results of my rolling road session can be seen below.

Please, please help!

I don't have any answers, however flat spots can be a sign of serious problems in the engine. Please get it checked for det and take it easy until you do.
