"dual boost" turbo is Honeywell manufactured.

Im curious as well.
Do the gave the same idea as the 6.0's did?
Or is it refering to the twin turbo system?

This could be interpreted a couple of ways. It has vgt and "regular vanes", which could be one way, the other way, there is two intake hoses into the turbo, one is "regulated" by the size of the opening, the other is more "open".

It isn't "twin turbo" Its one turbo, 2 separate vanes coupled by a single shaft. About 25 psi max boost.

That sounds like they're using one turbo in a way that some use two turbos in a sequential form. Yeah, I'm confused.

Only 25 pounds of boost?? Wow!

More is not necessary. If someone tries to "disable" the wastegate, no extra power will be gained.

Just curious, why do the older ones, like my 6.0 use more? Mine would go up to 36-37 stock. I guess the newer ones are just more efficient?

36-37 is far from stock. The 6.0 in proper form would develop 23-25 psi. 36 or above sounds like stuck vanes.

I still remember when I brought her home from the dealership that she would peak between 30-35, but I guess I'm wrong. I know that the 64mm hit 45 going down the strip.

Thanks for all the info you're posting Vince. It's very interesting!!

Interesting that there is a wastegate on a VGT.....do you think it was added mainly as a precautionary measure in the event of sticking vanes that might cause an overboost condition?

Note, it has VGT vanes AND regular fixed vanes. Weird, aint' it!
