My setup:

2000 Integra GS-R
JRSC @ 6lbs
Cartech FMU
B&M FPR
I/H/E

My question is the last time i was on the dyno i was running a little lean. 12.5 to 1. I am saving to get the AEM EMS but in the mean time can i just install a set of 310"s and lower the fuel pressure to get the mix alittle richer? Any help would be appreciated.

 

12.5 to 1 actually isnt too bad. If its not detonating....The car might be getting the right amount of fuel. any more and you could richen it too much and car would bog.

 

This is whats confusing me. I am running 60psi for a static fuel pressure (which i think is way to high) but when i hit boost my A/F gauge only goes to the first green light in the rich side (after i got it tuned it went all the way to the last light in rich). Seems to me with that much pressure it should be pretty rich. My FMU is also turned all the way up so that is why i thought bigger injectors would help.

 

well considering your FMU is turned all the way up....Your stock injectors can only push so much fuel. If you want to run richer....upgraded injectors would help. But remember, too much fuel isnt the greatest either!
