fuel pumps and injectors

[tylermartindc]

trying to decide on choosing new pump and injectors. my mods are in my profile for u to have a look. my question is, with the minimal mods i have, is getting a fuel pump such as walbro 255lph too much ? is it safe to run that considering what i have? and also how to choose injector size? im running around 12psi as of right now but the owner before me said it could run on 15psi. i dont see how it could have "safely" with stock pump and injectors.
any input is great.
thanks , tyler

The upper limits of a rewired Walbro 190 is around 38-40 lbs/min airflow depending on what AFR you tune to (assuming pump gas with a .76 specific gravity).

well i live in florida so im at sea level everywhere just about but 38-40 equals to about how much boost? But you think i should just stay with a 255 despite im going to be running mad rich with that and the 10 psi more n/t fpr with no tuning devices.
