All depends on how its mapped. I am now on a k04 at 2+ and the car ran 340hp on the dyno, tbh the car is far more manageable now than it was before at 2+ k03 as power at peak was through the midrange and started to die off at around 6k rpm . Now it just flies round to 7.5k rpm. Still an animal in the wet though. I dont even bother when the roads are damp now.
