Long post (questions, tips) about turboing a 6.2 with 6.5 parts

Boost master is the threaded rod that acts as a wastegate, correct? Rather than relying on vacuum to open the waste gate. Which i bieve is what I've got onnthe turbo I purchased. What are the pros n cons of that?

From a conversation that I had with an engineer ref the 6.2 vs the 6.5. Anything more than 6 PSI boost on the 6.2 is basically asking for a problem. 3 PSI is the safest boost he'd suggest, which would net about 15% increase in power and usually a bump in MPG if you can keep your foot out of it 3 PSI is a noticeable increase but 6-10 PSI will push you to 200HP over the base 130HP and all but guarantee a bottom end failure.. Banks had a turbo kit for the 6.2 and it was 7-10 PSI.
