Holley AFPR setting

I have a friend who has just installed a Holley AFPR and is running #24 fuel injectors. My question is, what fuel pressure range should he set it for? He currently has it set at 42 PSI. Any help would be appreciated, thanks.

what engine specs? and stock chip still?

if its a stock 350 tpi with 24 injectors, i would think he needs to lower the pressure from the stock fuel pressure setting.

i could be wrong though.

It's a 350 TPI with the Dickey Scoggins set-up.
