Trick hot side, Magnum Performance T70 q-trim with .96 turbine housing, custom cold side, LS7 MAF in 3.5" tube, Deatchwerks 60# truck style injectors, TI Automotive TU64HP drop-in 450 lph fuel module.
In regards to the fuel module I searched and searched and only came up with solutions where you needed to modify the fuel bucket. This engineered solution literally dropped in and all factory connectors were plug-and-play ... super easy. Measured fuel pressure at the rail was 58 psi +\- 1.5 psi and after the install was the same. I had heard rumors that this pump would actually flow too much fuel for the stock regulator to bypass. Went up into the mountains yesterday on a long slow trip and truck got plenty of work / hot and everything worked perfectly.
Awesome. I am currently running a racetronix 255 drop in module. I emailed TI just now about a 450 module like yours for the return style. How much was it?

About $380 through Jegs or Summit.
Based on what I've found TI Automotive is a large manufacturer / supplier of fuel systems for OEM's. From what I can tell they acquired the automotive aftermarket segment of Walbro and started offering pumps and fuel modules, even high performance versions, as part of their "TI Automotive High-Performance Solutions".
These pumps and fuel modules are now offered by Holley. I'm not positive that the TU464HP (TI Automotive's #) crosses to Holley 12-954, but it sure does look to be the case:
What are you turbo guys doing for exhaust? I want whisper quiet, yet high flow / low restriction.
I originally had my 3" DP going to a 3"-to-4" transition, into a m085171 Donaldson muffler (40" long, 37" body, 4" in/out, 8.5" body....straight thru), then out of the muffler to a 4" Duramax over the axle tailpipe with 5" tip. It was loud at idle, and just off idle, but the cruise and WOT were very acceptable. I did NOT expect this set up to have this much tone with my excessively large muffler!! I also did NOT like the way a 5" tip looked, so I ditched it and started to experiment. I took the tip off and that quieted it down some, and then I necked the tailpipe down from 4" to 3" right at the end, and that quieted it down further.
I then bought a 3" tailpipe and adapted it to the 4" muffler with a 4"-to-3" coupler. It has a 3" tip and this set up is just about perfect, but still has a little "rattiness" at idle and off idle to 1400 RPM. I'm making the assumption that my mega-muffler isn't getting a work out when exhaust gas flow is super low (idle / off idle), and perhaps I should have made the entire system in 3".......or 3.5"

2004 Silverado 2500 4wd Quadrateer turbo install....done
All I have are some pics from when I bought it from the previous owner.
