Default Mustang swaps - Which fuel pump?

To the guys with the Mustang conversions - What fuel pump are you running? 190 lph, 255 lph, 255 lph high pressure? Let me know what you got.

I also used a walbro 255, and I wired mine with a relay to the LS1 computer, so it cycled just like factory.

Ok, so I went ahead and got the 255lph unit that Trick Flow sells (probably just a Walbro or Holley rebadge). I probably could of got by with a 190lph or even less, but seeing as everyone is doing fine with the 255lph, then why not? Plus, I think the rating on the mustang pumps might be at the lower pressure (the 5.0 runs at 43 psi? vs 58 psi for LS1). So, I figured having the insurance of the bigger pump can't hurt. Thanks for the help.
