Boosted B6teen

Ok, I have a nearly stock B16 in my coupe. I had a shop install a Exedy stage 2, 3 puck ceramic clutch and XACT flywheel. My original Clutch master cylinder was blown so that was replaced. I drove it good and broke it in properly. I noticed the clutch engaged way up at the top of the pedals travel, even when brand new. After about 2 maybe 3 months it started slipping during normal driving, only after it had warmed up and only in kinda warm weather. So I called the shop and asked about it, he said it was the clutch slave. So i replaced it with new OEM unit and it has drove fine for the past 2 weeks. Now it is doing the same exact thing, slipping under NORMAL everyday driving, only after its been warmed up. Any help guys?
