What cases are these? An intercooler is an obstruction that will have pressure head loss across it. I could see how having a reduced volumetric flow due to a drop in temperature (caused by the intercooler) would have less loss through the manifolds, but unless it is huge, you will almost always have more pressure drop through a system with an intercooler.
Please research this issue further. This is not some unsubstanciated claim that I alone am making. There is also discussing regarding this issue at nasioc. More recently this was discussed in the built motors forum.
