I noticed that when my wife went to roll down the window at a steady idle it seems to bump into that loop a...

It has Pink top injectors and an M50 Manifold and I purchased a 1995-1996 BMW M3 MAF Part No. 13621747155. The chip that was in the DME when I bought the setup seemed to have been the stock M50 chip...
