As you said, one of the best ways to burn up smoke is install a turbo or turn up the boost slightly.
In my 6.5L diesels short life as a non-turbo it did smoke a little bit, then after I put the first turbo on that got rid of nearly all the smoke and improved fuel economy 2 to 2.5 mpg or by almost 10%.

To further reduce smoke production and engine oil consumption on my 6.5L I machined the heads so I could put actual seals on all the valve stems. The intake valves had something that barely resembled or functioned as a seal and the exhaust valves had nothing.
I didn't have to do it but I did.

1984 chevy suburban, custom made 6.5L diesel turbocharged with a Garrett T76 and Holset HE351VE, 22:1 compression 13psi of intercooled boost.
1989 firebird mostly stock. Aside from the 6-speed manual trans, corvette gen 5 front brakes, 1LE drive shaft, 4th Gen disc brake fbody rear end.
2011 leaf SL, white, portable 240v CHAdeMO, trailer hitch, new batt as of 2014.
