    7 months ago I had a very trusted and reputable performance shop install a clutch on my speed3, I went with the classic Luk+Fidenza combo, well one day last week doing pulls it slipped badly, and still does only in full WOT tho, normal driving is perfectly fine still, I need help on what could of been the issue or why this is happening only 4k miles into the clutch, I have TIP,SRI, HPFP, a tune from Freek, BOV and catback exhaust, I've read the OEM clutch can handle plenty of power even big turbo setups run it ,cause I really don't think it was the shops fault the clutch was perfectly fine till now, keep in mind everything else feels completely normal as well, just slipping in full boost. any advice on what to do next? should I just get a stage 2 daily or stage 3 daily from southbend? or should OEM be handling it just fine ?

    The accessport log gets dumped into vydno (another program) to output a graph like on a dyno. It would graphically show if your clutch was slipping.

    Update: went to get WOT logs for vdyno, clutch would not slip at all, I have beat the shit out of it today and it will just not slip, last week I could barley build factory boost without it slipping, i am so confused…

    If the clutch pressure plate springs are weak or if it's cracked it can cause erratic engagement or slipping. The only way you're gonna be able to tell is if you pull the transmission off to inspect the clutch.

    It's also possible the slave cylinder could be sticking and not moving easily making the clutch stay partially disengaged or not fully engaged when driving.

    You could have a fluid leak onto the clutch disc causing contamination of the disc material.
