2 why would you do a filter when the car wont start unless its jumped
From what info you have given it could be a lot of things wiring, ecu, senors, and what not.
So more info is need like is the car stock, year, and what ever any one here will ask.

so at one point you didn't have the "whole stock intake piping"?
answer:
1. did you ever remove the AFM? If the answer is yes, answer then how did you unplug it?
2. did you remove the hose that attaches below the throttle body?

answers
1. just from the plug on the side , when it was on boost it didnt have it , the plug was just hanging in the bay
2. the hose on the bottom of the throttle body is plugged in to the stock intake piping where it goes its the L looking hose

My next best guess would be the tps sensor. But before you go messing around with that try something for us.
pull your air filter off so you can see the inside of the AFM. With the car running push on the vain on the inside of the afm while trying to rev it up. The more push on the vain the more fuel it will dump into the system.

so this is where i stand so far: my friend has a spare AFM laying around that didnt have the cap on it so i used that and the car would still do the same thing, so i went ahead and tried his daily one and it worked a little better. I then went and put the AFM without the cap back on it and wedged something in it so it was about half way open. When i did that the car would bring the RPMs up when accelerated but after about 3,000 it would bog a little bit but i have a feeling its because since it was wedged its only telling the fuel pump to only inject so much fuel. Im thinking i may just need to order a brand new AFM?
