how far can a racetronix 255 pump go on boost?
I currently have full bolt ons, blower cam, 6.0L heads, and a procharger running 6 pounds of boost. I am using a racetronix pump with their wiring kit along with 60 pound injectors. I do have a boost regulated fuel pressure regulator but I don't have that installed, which I am not sure if it will help. I would like to raise the boost to 8 pounds. Can this pump keep up?

that 255 pump will only really supply enough uumph for 51.3# injectors (see fuel & injector sticky here: https://ls1tech.com/forums/2638447-post1.html)

Injectors and boost are irrelevant.
The power you are making is very relevant. in the UK a single Walbro would be at it's limit at around 500 flywheel HP.
It seems to go further for American rwhp though.

On a built 6.2 w/ cam and KYTP turbo kit..9psi and made just under 600RWHP and tq on a single 255. Fuel pressure is still staying up in the higher RPM range. But I would add another pump.

each and every pump has a flow curve, i know this.

To answer the questions in the first post,
That pump with the FPR will likely hold you, but it will be close.
Going with two pumps (255 s) would greatly benefit you and increase your maximum injector capacity.
