Adding a bigger turbo to the single systems will net these peak numbers or greater. I'd bet the single is cheaper as well.

Boost is boost and as long as the IAT's are managed, there is consistency.
The singles are a good setup - twins are just a different approach. Properly sized twins will spool up at the bottom and carry big on the top;....conversely and in general terms, a single that hangs with a twin setup on the top will be at a disadvantage at lower RPM.
No big deal - just another way to look at at.
