Compression ratio doesn't affect the engines braking ability a whole lot. Much of the energy that is used to compress air on the compression stroke is returned to the crankshaft as the air expands on the powerstroke.
When an engine is working to hold back a load it is being used as a big air pump. The power to pump air comes from the torque and rpm placed on the rear axle by the grade and speed. The more air being pumped and the higher the pressire at which it is being pumped at, the more power is consumed. So if the boost has been increased to 33 psi from 25 psi then the new engine should be capable of a significant larger amount of engine braking.
I'm surprised they're pushing that much more boost just to gain a few more ponies.
