I like the idea of a single turbo, even if it makes the exact same power as my current stock appearing compound set up, because of a few different reasons. The single makes getting to the HPFP, oil cooler and the valley in general a lot easier due to being a lot less complicated to get the turbo/pedestal on and off the truck... especially with having such easy access to the up pipe bolts. It drops the back pressure dramatically. In the event of a turbo failure, a billet s366 cost approx. $1200?.. or if your running say a s371, that costs $1600. On the flip side, a set of factory compounds is going to cost atleast $2500, never mind if you have upgraded aftermarket stock appearing turbos that are much more expensive than that. Maybe I'm different, but I look heavily at the serviceability side of everything and that's always a major factor in what I choose.
Might you loose a little bit of spool and instant torque, yes... But with the right tuning it wont be very different. I'm also by no means trying to start a pissing match here, just bringing up some points that may have been over looked by others when deciding on this option.
