Clutch slipping after rebuild

[LeeSD1]

So i just finished putting a fresh rebuilt motor in but I used the clutch I was running before. its a spec stage 2+ but it only had a couple thousand miles on it because i put it on last summer and lastnight i took out the car to break in the motor and it was holding fine until all of a sudden it started slipping. and it slips REALLY easily. Not even 3-5psi of boost and it starts to free rev.
Could this be anything else besides a bad clutch? could it all of a sudden just start slipping like that?

Is the engagement the same as well? or does that clutch grab at a different point when letting the peddle go? If it does, you might have to adjust the clutch engagment and see if that helps.

It feels completely the same as from before I took it off. I even adjusted the pedal to not put pressure on it. And it feels so bad when it free revs a little because when i let off right when it happens you feel the clutch instantly grab and jerk. Im guessing the clutch disc got contaminated when it was off
