i suspect this would cause problems with running lean. if the computer thinks there is less air going into the engine than there really is(or warmer air) it will inject less fuel. yeah this could effect fe in a positive way since you are injecting less fuel, but i suspect that running lean for extended isn't any better for a Diesel than it is for a gasoline engine.

NOTE: I am not, nor have i ever been an expert in regards to diesel engines, this is only my thought as to what would happen
