What's the max rear wheel horsepower ever supported with a stock TBI fuel pump?
I've read the max flywheel hp for a stock TBI fuel pump is about 300 hp. This would suggest between 245rwhp to 255rwhp is possible.
What fuel system mods are needed to support ~300rwhp to 350rwhp? New pump? bigger lines? etc?
Likewise, if a TPI fuel pump has an adjustable pressure regulator on it, how much more rwhp can it support than the TBI pump.
Any info appreciated in advance.

With a carb an a TBI pump where I only need 6psi and I use a vacum AFPR to completely close the return line, a lot!
