Can someone with a 2008 Impala ss Please take a couple of good pictures of the intake manifold and the MAP sensor & location. Also the part number on the MAP sensor. These components are an upgrade from the original 06 version for performance reasons.

I thought 05-06 map right behind the TB on intake neck and 07+ map was moved further back for performance reasons, what was changed for the 08's?

I am unaware of the 07 being moved back from on top of the TB inlet manifold side. With this said the info I have says , the intake and map are changed in 08 for the Impala and the Buick Lacrosse. Also the new map is faster and more reliable at wot and high rpm use.
