Any time you have flow through a tube you have a LOSS of pressure, becuase it is a restriction. The tube DOES NOT increase the pressure, it increases the restriction. That means the air on the inlet side of the turbo is at atmosphere minus the loss due to the restriction of the entire intake tract.
That isn't even debatable. It's a simple fact. The only questions here are how much loss the tubes present, how much it would cost to replace them with larger tubes, and whether or not it would be worth it.

Sorry if I came across wrong, I agree 100% that there will always be a pressure DROP across a tube. I was just breaking down the components of it as there seemed to be some confusion.
