Unusual idle after clutch install

[eagle talon guy]

I recently replaced my clutch in my '93 Talon TSI. After we got it put together, it idled weird. It sounds like it is cammed. The needle on my boost gauge "shakes" a lot around 10 psi of vacuum. It's weird because it runs great, it's just weird when idling. I don't know what could cause this, but it's not normal, and i would really appreciate any advice given.
If there are any questions that would help you diagnose it, please ask and i will try my best to answer.
I will try to post a video soon.
Thanks
