Cleaning up vacuum lines

[GooeyGus]

Hello,
I remember reading somewhere that almost all of the vacuum lines connected to the throttle body could be removed, and that one only needs the nipples on the intake manifold to run the car.

Can anyone go in-depth a bit more? What vacuum lines are 100% necessary and which can be removed?

I know I need:

FPR
BOV
Boost controller
waste gate

I have vac lines running EVERYWHERE and I'd love to get rid of them. I think I even see some running to the coolant temp sensor??

My car is a federal '90. No EGR to worry about.

So, what do I have to keep and what can I rip out?

Thanks!

fpr and bov run off engine vacuum,, boost controller and waste gate run off of the turbo vacuum hope that helps some.

Vacum for bov, fpr boost controller. Thats how my car runs no other vacuum lines. I have my bay looking great but it will be done this winter, very clean.
