single vs twin.
there isn't really any advantage to either, imo, it comes down to preference and packaging.
can you fit a single and route a crossover tube from one side to the other, in your truck, yes!, so i single would be an option.
most of the time you'll find vehicles equipped with twins because of routing issues, or they just prefer twins. for example the tight engine compartment of a vette.
it does cost a little more for twins, but if anyone is considering a turbocharged truck, they shouldn't be worried about their budget, if so, leave it alone.
it's too tempting to turn it up, things break, etc...
also, before you build or consider solution, ask yourself how you plan on using the truck and the goals you wanna accomplish.
big or small turbo, injectors, transmission, cooling, a/a, a/w, rearend, fuel system, power level, etc.

what I understand is , the twins have a wider power band
for example
the S480 will spool late on small cuped engine like the 4.8 or 5.3 but will pull hard in the upper RPMs
and the 67mm will spool faster but dies upove 5500RPM
but twins will spool fast like the 67mm and still pull up like the S480

and the 67mm will spool faster but dies upove 5500RPM
