SR20det shuddering after piping pop off. VIDEO

[lg54]

Hey guys

Please help me out here. Coming home, one of my pipings popped of as i was entering boost. I quickly went to one side and fixed it. I went slowly home as i was running out of gas too. When i get home, i notice the engine was shuddering on idle and it turned of. I proceeded to add gas thinking it was gas, but no. Also, went ahead and checked for vacuum leaks but could find any. My engine was running perfectly until the hot side piping popped off. Please help me out, what could this be. Also, it shudders and hesitates on low rpms. THanks

Boost leak? Injector leaking? Throttle body not opened correctly?

Ok so updating this thread. I think i found what the problem was. It was a vacuum line connected to the PFC maf sensor that was unplugged.
