2010 C-15 Acert Question

I haven't been in these forums in a few years, but I'm back in a 2011 Pete with an Acert motor and it's the first one I've driven in my career, and I don't know a whole lot about it. It has the burner/spark plug setup and we've been having some issues with it.

It's under an extended warranty, so no modifications have been made to the motor, so my boss isn't going to gut it for a simpler running single turbo setup. A few weeks back, blew off the small 1.5" hose that goes from the front of the turbo to a control solenoid. 2 new clamps rectified this. I attached a similar picture for reference.

Driving the truck - it will start by holding around 30-34 lbs. boost. Kind of sluggish - doesn't seem like a real powerhouse for a 475. Then, every once in a while it will jump to 40+ lbs. of manifold pressure, and the noise from the air cleaners is insanely deafening - almost like ball bearings doing laps inside of them. Runs stronger, but I'll find myself backing out of it to quiet it down. It'll run this way, and seems to "shut back off" after you come into traffic, the radiator fan kicks in and cycles and then it's back to 30-34 lbs. of boost and peace and quiet.

I tried reading similar threads and Mr. Haney mentioned that most Acerts should be up around the 45psi mark, and from what I remember, he really knew his stuff. Truck isn't consistent with this, so I'm kind of miffed as to what is going on. I know he hasn't been around in a while, but anyone who could point us as to where to start would be a big help.
