190 lph or 255 lph fuel pump

[AWDfrank]

I decided to go with a ported 14b instead of evo 3 16g in order to cut my cost down.

With only a 190 lph fuel pump and stock injectors, what boost should I run at the most with pump gas?

Would a 255 lph fuel pump with stock injectors be a bad choice, if not what boost could I run on pump gas with this? ( 91 octane )

Is an aftermarket fpr needed for a 255?

I know boost depends on a lot of things, ill have a safc2 to tune and a datalogger to keep an eye on things.

What pump would be best for a ported 14b on pump gas, stock injectors and fpr, is my question mainly?

To jump in,

How about and EVO3 running on a re-wired 190, 650s, AFC, and a pocket logger looking for no more than 300whp?

also jumping in big t28, 650cc, 21lbs, sufficiency.... 190 or 255?

190lph will be fine.
