So I have noticed that while driving when boost kicks in and I throw in the clutch my engine revs a little. When more boost kicks in around 10-14 psi it revs higher, like 1000 rpms. I just had the clutch replaced last week hoping it was just the throwout bearing causing this but sure enough problem is still there. I have looked around and cant find anyone with similar problem. Car runs great but I just cant quite figure out what this is. Any input would be great!
