This is the first time I have ever seen a statement like this. Turbos have been used on diesels since forever to boost HP - John Deere tractors, semi's, etc. Long before there were any emissions standards at all.
In fact, possibly the coolest diesel car in existance - the Audi R18 Le Mans racer, gets approx 500 HP from a 3.7L turbo V-6. I doubt that the turbo is on there for emissions reasons.
I'm really not trying to be argumentative as I assume there's a little more to your statement. I'd really like to know what you mean.

More boost will reduce EGT if you don't add more fuel but they are there so you can add more fuel and make more power.
