The torque curves are not bad at all for the turbos we're dealing with, but of course I would assume that you would like them to spool up a bit sooner than that for a road-car use.
I can't help but feel that a reliability of 71.4 in a 2015 V8 engine for the parts you've likely selected is a bit on the low side despite everything else being quite good. What's holding it back, the boost? The redline? Judging by the PU and materials cost, you haven't touched the tech sliders either, and if you want it in a high trim level brand car like Audi or BMW, you could probably afford to put some money into the valvetrain and/or the headers. That won't blow out the costs too much and probably get you closer to a 76-77 reliability unless you're running highly undersquare.
