Default AFC hack turbocharged and my fuel pump

"AFC Hack - Fuel compensation for this setup is done by installing larger injectors. These higher flowing injectors allow more fuel to flow through during the same pulse duration to compensate for MAP signal scaling (which decreases fuel flow). No fuel pressure regulator is needed. No upgraded fuel pump should be required. This setup is normally good for ~10psi."(found in the FAQ about FM)

so i dont need to buy a 255lph fuel pump to accomidate for my turbocharger. I will be putting some DSM 440cc injectors in my b18b(ls integra). I probably wont go higher than 10psi. But when i do, i would need to use a different fms and a fuel pump too...right? anyone know what the stock fuel pump on a 95' LS integra? i have been searching and i can't really find anything. thanks

Well, the AFC hack isn't exactly "safe" to go over 10psi so no matter what fuel pump you get, it still won't be a good idea.

If your fuel pump is working properly, you don't 'need' to upgrade to a 255, but it couldn't hurt.

I've seen several people run the stock pump with the hack and they had no problems. Of course it's a good idea to run one, but I wouldn't say you have to.

I've got a stock 91si that came with a 255 in tank. Anyone have an idea what % I should take outta the fuel maps to compensate a stock running engine with a 255?

Running turboedit btw.
