ive got no performance mods, just a short shirter and a berk WAI. all my mods are sound system related. im guessin i should just stick to the 87. i filled 89 and i thought i was noticing more power but maybe i was just imagining it
:wall: nismo recommends 89 octane after cams installed
from experience: tank of 87, no noticeable power; tank of 89, power is definitely present.
