Hi all. My clutch is slipping on full boost(20psi) and i sometimes get a judder as it starts to slip.The clutch was changed on the car around 6 months ago. The pedal has also gone light. What could this problem be? Car is a 2001 wrx running 340bhp but never launched it or gave it alot of abuse. Also only covered around 3k miles since clutch change. Bite point is fairly high aswell. Any advise would be great thanks
