Take a look at the temperature difference between manifold exhaust port #1 and the turbine housing. I'm thinking that retarded timing is not burning all the fuel in the combustion chamber and allowing the fuel to continue burning in the exhaust; creating more heat outside the cylinder. In some situations that can be desirable but this, I do not believe, is one of those situations.
