where the hell are you getting these readings?
yes, the stock and aftermarket pumps are capable of up to 80-90psi
but the stock regulator should be set for around 40psi
aftermarket regulators dont normally go above 60

if you are getting that much pressure, your regulator is bad.

really u think my regulator is bad, i can turn it up and down and watch my fuel pressure go up and down with it, and i am getting a 90 psi reading from my fuel pressure tester and it is accurate

either the regulator is bad, or your gauge is wrong.

i cant figure out why i am running lean on 24# injectors anyways, that should be enough with the mild mods that i have anyways, all specs show stock runs 70 psi of fuel pressure

no way man. there isn't a car in this world that runs stock on 70psi.
factory setting is 39psi, about 46-47 with the vacuum disconnected.

a new regulator bad, im starting to get a migraine from this car, im about ready to sell it or something, it runs good at idle but when u throttle it or drive it it really leans out enough to glow my headers and im worried about melting the pistons out of it
