^^you have to adjust your shifting techniques to compensate for this. This is normal on our cars, especially while under more load. More load = more throttle = turbo spooling = rpm spike when you quickly let off the gas. Let off the gas for a brief second and then clutch in to avoid this. It happens to me everyday at least a couple of times. I've learned to shift at 7K RPM so this does not happen, you just have to get to know how your car responds a little better. When I first got the car, this happened to me all the time at WOT...at first I thought it was the car, but it's somewhat the driver's technique as well.
