In regards to smog, that is the great thing about the 7.3, although a smog test is required, it is mostly a visual inspection and none of what is being done will change the visual aspect of the truck unless you really know what you are looking at. The only real visual change will be the turbo but we are specifically going with one that looks very close to stock (isn't shiny) so you would have to know what it is to know what it is. Some 99 7.3s came with a catalytic converter, some didn't. It's a bit of a grey area on this truck and one of the reasons I opted for it over newer trucks.
On my 6.7, they plug into the OBD port and check that the ECM hasn't been "tuned". I don't remember if they did that with my '99 7.3 or not. On a 7.3 there isn't that much as you say that would be a visual givaway. The usual "delete" on a 6.7 would be quite obvious visually.
