My 340lph with standard regulator is fine at 460 so I'm sure with a regulator the 450 will hit those numbers

I wouldn't count on a single in tank pump for those kind of numbers... 550 on vpower is questionable on it's own. You didn't mention if thats measured on the wheels or the crank?

yes we have had 450 kits outflow Bosch 044's and support cars running into 600.........

you need to look at the overall fuel system though and not simply a pump
