Too many people read into turbos solely their PSI. PSI is only an indicator of resistance in a diesel engine. More PSI doesn't automatically mean more power. Increased CFM at the correct point in the turbo's map does.
That said, I don't have a C or D turbo map, but I do not believe it would make a good turbo candidate for a 6.2. Based upon the fact that they both operate in a close RPM band. (I don't spin mine past 2800rpm when it comes to the 6.2, 2700 for the multi) While it could certainly provide an ample amount of cfm to the 6.2. The problem would be spooling it. Or the likelyhood that it wouldn't spool until you're spinning the 6.2 past 2500+ rpm. Kinda defeats the purpose of a street vehicle.
