i just got my fpg and fpr for my b16 in my 91 hb, i was wondering what should i set it at for the best performance and at the same time not waste alot of gas. right now i only have the fuel pressure gauge(fpg) on and it reads at 30 psi.

 

Put it to the STOCK 38psi... If your motor has mods which can use a lil more gas don't be afraid to dump a bit more... Latez

 

unless ur boosting, u will probably not need need the fuel pressure far from stock, stick to 38-40 psi, and it'll be fine
