So I know nothing about how a Y-pipe would affect anything, so I am just going off what I have read and could be wrong... but didn't someone say that a Y-pipe would cause different air flow to go through to the two sides... like one side could be getting more air than the other causing MAF to read wrong or something... Someone educate me here please? I thought a simple Y-pipe wouldn't cut it?

I would assume you are talking about coming from the turbo.... You would have your headers, to test pipes/Cats, to a Y pipe, to the turbo, Then you would have one charge pipe from the Turbo to a 1 inlet 2 outlet intercooler that would split the air equally to the 2 mafs. Granted im sure it wouldnt always be a perfect distribution. im sure it wouldnt be much of a difference between sides. Remember the 2 intakes feed the same chamber in the intake plenum. Air pressures would equalize pretty quickly. If each intake only fed one bank of the engine then you would have to make sure the boost coming in was equal.
