ya bigger might do that, but look at the tuner market they offer larger turbos all the time for power upgrades. yes you would lose a bit on the upper end but would have a higher airflow on the top end. so for a low rpm diesel it would have to matched to give you best power for range of rpm you highway drive at.
all this comes down to is more choices for a setting up a perfect combo.
it might not be practical or worth it for many.
the turbo I picked isn't that big, I will have good bottom end I presume.........
