What is the main benefits of going return style vs. just bigger injectors like 80lb?
Edit: OK so I have learned that general fuel control is simplified with a return style with less ramp-up in fueling.

At the moment I'm assuming the maximum output of the stock fuel pump is what is the limiting factor when we're talking about moving to a return-style system.
At some point the stock fuel pump just can't flow anymore, regardless of injector size. THAT is when I figure a return style fuel system is required.
