Returnless fuel system

[sparkinak]

I used the corvette style fuel filter with built in regulator that has the return built into it. I have been reading the info on here but if I understand it right as I have ls3 injectors at 58psi, pretty much means no matter what the injectors are putting out 42lb/hr fuel. So would I be better loading that OS onto my 411 pcm or can i continue using the stock 0S from 02 denali (but with ls3 data)?

Hello. What os do you refer to, ls3 in 411

I have done this many times on Tahoe and vette. I use the same os, change the flowrate on the injector only

I meant to ask on the ifr do i change them all to 42lb since there isnt a way for the pcm to vary the injectors?
12212156 is the os im using
