wut is a good psi for a ls integra .. mods are intake header full catback!! so how much should i crank it uo to?

 

with those mods you dont need to crank up anything, especially when gas is $3.00 a gallon. I am not sure what the stock fuel pressure is on an LS but thats all you need.

 

well stock on an ls was around 25 to 30 psi . and my homie with a da is on 48psi and his ride flys i mean flys thoe.. anyway thoe i always see black smoke when he halls ***.. is that good or bad thoe.. but wuts a good psi thoe????

 

Stock is 40-47 for the LS (Page 3-6). You measure with the vacuum line disconnected (it reads lower when it's connected). With your mods, you might be seeing 10 hp difference in performance which means...run stock pressure. If you're really running 30, it probably runs like ****.

Your homie's just tossing gasoline out the tail pipe and probably wearing his rings out by washing the oil off the cylinder walls.
