I see where you are coming from with your research. It is perfectly norml in a turbo diesel application. My 6.0 and 6.4 had turbo fart in stock tuning with cold air intakes installed. A blowoff valve will remedy the situation but you have to look at the cost of that. There are guys running big power numbers who have turbo fart and don't run BOV setups.
But, if you are dead set on getting rid of that, a bigger turbo may help it some. I had a 5.9 Dodge that would fart occasionally and when I installed an Aurora 4000 turbo, it went away. (Truck was a six speed) Or you can run a BOV. It's your choice where you want to spend the money.
