Boost?

How come the new 6.7l doesn't run as much boost as the 6.4l or the 6.0l? My 6.0l has seen 35 pounds when I was towing on a stock turbo. Now the 6.7l uses around 25? Can somebody explain that too me?

Boost and power are not directly tied to each other. They are related in a turbo diesel but can vary greatly. Even though its "only" 25 psi, its very likely still flowing more air than a 6.0 at 35. CFM is what is important. Boost is more or less just a measure of restriction.

Yea, it's kind of like this:
There's 55 lbs of air in my 35" truck tires, but 60 lbs in my bicycle tires.

More pressure doesn't mean more air.
