Attached is results of an experiment of adding an intercooler to a turbocharged engine and keeping fueling the same.

and finally here is a link to a book on diesel engines. If you want to do a detailed analysis or partial analysis of how intake air temperature will effect things by plugging in numbers to equations this book will show you how.

I can dig up some further studies and papers by NACA that show a similar trend if you like.

Edit: added the words "the same" after the word fueling

This looks correct to me, and verifies what I said.
Thank you.
