how to tell if clutch is slipping with turbo?

I have a relatively new spec stage 2 clutch (that I hate.) I run the FSWERKS stage 2 kit. At about 3200 rpms, the turbo really spools up and the rpms climb quickly....but it doesnt feel like the car is actually pulling all that hard.

I do need to get my tune dialed in. I was wondering if this feeling might be the clutch?

If you see the RPM go up and the spedo not go up then your clutch is slipping , you can confirm this with a datalog looking at the right things

drive around 35 mph, put the car in the highest gear and floor it. If the rpms rise quickly but not increase in speed your clutch is slipping. If the car bogs down and is slow then your clutch is fine.

The slave cylinder included with it, broke as soon as it was driven off the lift....costing me double labor costs.

But the real issue I have is...its unpredictable. I could be at a stoplight and let off just a bit and the car will start to pull....good. Other times, I have to let it almost all the way out and have the car shuttering before it starts to pull.

Master may be leaking and/or vacuum leaks not letting raise enough pressure sometimes, any will make you abuse the clutch, don't like spec either but an issue like that could happen with any brand.
