Using an SR coldpipe and bogging and stalling

[Rusted_PS13]

I'm using an SR coldpipe, and I'm having a problem what one of the "sub-piping" is for. The following picture basically explains, right now I basically have the big fitting plugged up with a rag, any better idea? Now for the bogging and stalling part, it doesn't seem like it would be my MAF because it is dying right away at start up and the only way i can keep it going is to give it throttle at start up. Even so, it will bog like it is a bad MAF and shows some smoke from the exhaust. My set-up is as follows:Car: 1995 Nissan 240SX (OBD1 or OBD2, how can i tell?)Greddy TD05-18G, Ebay manifold, ebay intercooler kit, stock fuel system besides z32 fuel filter (don't worry, i'm working on this) , no tune yet (gotta get it running good), K&N Air Filter with stock MAF

The big red one is for BOV recirculation. If you run atmospheric BOV then plug it shut or cut and weld shut. What do you have for fuel? injectors? fuel pump? FPR? Need more specs on your system.... Disconnect your mafs see how it runs you don't need it to start your car and to have it idle

Stock fuel system, my set-up is stated above

Your car should idle fine... You got a leak somewhere... I have a s14 outside with fuel pump and fmu and almost same/similiar everything else

I just went look at my car, and the rag popped out of the pipe, guess i gotta find a more suitable way to plug it up :/

Ducttape on mine.. Piece over it a couple times and then wrap around the pipe to hold the pieces over it...

Ugh, i've got the cold start issue sorted out, it was related to the huge sub-pipe, but now when the car get's warmed up, it'll bog/stutter/run like crap throughout acceleration and it will also stalled when off throttle. Fuel system? maybe, Un-tuned? Maybe...i can't figure this out
