Yes, i agree. Using the jet flow chart im currently at 25% more flow on the pri with pvcr and main jet combined over the secondary jet. According some posts iv seen on racingfuelsystems some suggest 10% over secondary jetting to as much as 25% more on pri to compensate for lost flow thru the pcvr channels. Anyone know how accurate that is with a dominator? My current jetting is 82/90 with 75pcvr 1100 dominator on a 511. My wideband shows 12.5@wot in 45* weather. Im sure that will be too fat in 80* weather.
