does an aftermarket fuel rail have some kind of performance value if you are still using stock injectors? been looking at this

Not even a tenth of a horsepower.
Power is related to the engine breathing capability Displacement X RPM X Volumetric efficiency.
If you had fuel pressure drop issues like with using a fat turbo with huge injectors, that would fix it tough.

i do have the blitz compressor but it probably wont make a difference sending the fuel from stock to perrin's fuel rail

correct. it won't deliver more fuel, and it if did, you'd have tuning issues.
