I don't think that would be the case in a diesel engine. That would happen in a gasser, but not a diesel. Diesels run on an excess of air. When all the excess has been used by the fuel, you get black smoke. You can dump all the air you want into the cylinders and it won't do anything unless you add more fuel. How come those who crank up their turbo boost without adjusting the full load in the IP don't overheat all the time? They may be increasing the EGT's, but that's only due to the fact that the turbo is increasing the intake air temps because of the higher pressure, not because of a leaner burn.
