Noob...first EFI LIVE attempt questions on standalone harness pcm changes

Next question....fuel system

The engine came w/ an '05 intake and returnless fuel rail. I didn't want to use the 'spensive corvette filter/regulator.
So, I just swapped on a return style fuel rail.

Is there any changes that need to be made to the tune for this?
I don't know enough or how to tell if an '03 (or the os I'm using) was return style or returnless style.

Form what I can tell in the Vehicle Platform Options, the '03 OS does not show any options for fuel delivery.

Looks like '04 is when they switched? All the '04 and later files I checked are different for injector flow.
So looks like I'm ok using the '03 stuff, and don't need to change anything?
