Does switching to a larger throttle body do anything?

I have a 2000 5.9 magnum. I got a twin 50 mm throttle body. Does it do anything for you to just change out the throttle body?
Or is that like bolting on a 750 vs 600 on the same engine?

(I got a twin 50 mm throttle body)

I understood stock was like 48mm due to a taper in it, or something like that.

Just wondering if switching out to a 50 does anything if that is all you change.
