Well, the car is fixed!! One day at the shop and they got it all sorted, they even dialed in the boost controller for me. Turns out the problem wasnt with any of the vacuum lines or things I installed.
It was running on three cylinders because the #1 fuel injector harness connector was not working correctly. $17 in parts was all it took to fix the thing. Im so happy, I was worried it was gonna be a huge ordeal to fix. Thankfully it wasnt!
I really want to sincerely thank all of you guys who helped me out in this thread and gave me advice on things to check. Really a great community of people. If anyone is ever in the Raleigh, NC area dont hesitate to shoot me a PM.
Moral of the story, old cars break the most random things so be prepared to do alot of detective work if your not a master mechanic...or just take it to a good shop haha.
Thanks again guys!

An $11 dollar noid light and fifteen minutes would have found this. I am sorry I did not mention it.
Great to hear you have it straightened out. Enjoy your car!

Took the car out on the highway to see how it was running. The engine seems so much smoother and quieter than it was before I was having problems. Also I am now getting 17in/hg vacuum when warm, before I was getting 15ish. 17 is pretty healthy correct?
The mbc is holding 11psi rock solid too. I wired in my boost gauge light, put some silicon around the holes I drilled and put everything back together. Running like a champ!

Chasing a similar issue, I stayed up until 3 am last night and managed to replace the ISV and TPS without pulling the intake manifold. There's not much lighting in the parking structure where I keep my cars, so I was working with a flashlight.
After buttoning everything up (or so I thought), including having to jack the car up and pull the engine pan to find a TPS screw that I dropped, the idle was now stable with no surging, but it still didn't feel right and the engine had a weird vibration.
I also noticed a slight tapping sound from the belt cover indicating I probably should've had the belt retensioned and I'm booked at the shop to have that done on Monday, but after reading your thread I realize that I left the #2 spark plug socket off, so I was running on 3 cylinders too! I know there is no excuse, but bad lighting is one of the many things that suck about not having your own place to work on your car.
Now I can't wait until lunch break to go back to the garage and check the idle again with the #2 cylinder running as it should.
Rennlist never ceases to amaze me. You try to help people out and never know when the favor will be reciprocated, whether intentionally or by total coincidence. I would've felt pretty stupid taking the car in on Monday with a disconnected spark plug. 5speed300, my thanks go out to you as well!
