Don't the new non-modified engines also emit less than the pre-2003 emission vehicles you speak of? Are you saying that a deleted vehicle with the emission system severely restricted or removed produce no more particulate (soot?) than a gasoline engine?
Yes, due to variable geometry turbos, better turbo blade technology, common rail, precision injectors that have multiple injection events, higher pressure fuel pumps, cams deigned for emissions, and a few other things; a deleted modern diesel on a low level tune has better emissions than most pre-2003 trucks. The removal of sulfur from the fuel also helped out a lot compared to the fuel back then.
Not all gas engines emit the same same PM as a deleted modern diesel, but many directed injected gas engine do. However, due to the composition of gasoline and diesel fuel and how fine the PM that GDI engine emit in comparison, you will see it out of the tail pipe in a diesel engine but will not out of a direct injected gasoline engine.
