mine was running pretty rich..about 10.2 on most parts of the power band (compared to the ideal 13.2-13.5)
i got a v-afc to straighten that out though. and i highley recommend it. and it saves you some gas
(if you keep the thought out of your head that it is faster :naughty: )
but from my experience, most cars, especially modded ones, run rich.
i've seen some cars run in the low 9s on a fuel curve. that's freak'n pewp.
just get a v-afc or s-afc (if you dont have vtec) or some other kind of fuel controller and take a trip to your local dyno.
