i got a FRP and gauge at modacar and i need to know what the stock injector size is for my 91 ls, also what’s the stock fuel pressure? when i put my gauge on im pretty sure it said 39.5, but that seems a bit high. anyways what should i set my fuel pressure at? i have an intake and cat back.
n e 1???
I think a search would have turned up the answer, but betweein 37-42psi is basically stock. I’m not sure what the stock injector flow rate is.
injector flow rate is 245cc.
