i plan on runnin some zoomies this labor day to race with. we run 1000ft. and i thought maybe the zoomies would add alittle pull to my midrange. anyways i went out yesterday runnin my twisties with o2 sensors and i'm runnin a steady 12-12 1/2 to 1. since the zoomies don't have a spot for a o2, and their borrowed, will it lean out the motor alittle??? will be runnin race fuel 110, 34 total, 8-9lbs boost.
