I do know higher EGTs spell death for a diesel engine, so it's best to avoid that scenario.
Higher boost lowers EGTs when not accompanied with increased fuel. The reason is that there is more air to heat in the cylinder with the same amount of fuel. Note that a diesel doesn't get hot when running lean like a gas engine.
