The IC reducing boost will help maintain the head gaskets and motor parts, but it in no way will save the turbo life. The turbo will see the same boost IC or not. The IC will reduce boost at the manifolds but not on the compressor of the turbo. The boost is decreased because of the air running through the IC. If your boost gauge reads at the manifolds (like it should) than the turbo is still seeing higher pressure than that.
Make any sense? The IC will not save your turbo from to much boost. Boost numbers will be different pre and post IC.
