Generally speaking, the charge cooler is an efficiency device.
So if the ambient side is 80 deg F and the turbo outlet is 300 deg F - the efficiency is a fraction of the temp delta. So an 80% efficient cooler has an outlet temp of:
300 - [(300-80)*80%] = 124 deg
If you drop the inlet temp by ten
290 - [(290-80)*80%] = 122 deg
Not much, right? The heat transfer efficiency will move around a little, but not much
You are more likely to pick up more power from reduced restriction in front of the turbo, and therefore less wastegate is required to make the desired boost, so lower backpressure.

This was roughly how I originaly looked at it.. I'm going in circles  Well, at least I qualified my statement with "If the post intercooler temps are lowered the same amount"... I should have figured that the one part I hadn't looked at yet would be the one to break my results
