aside from near death experiences while initially entering traffic.................I am pleased with the 12 to 13.5 mpg Ive been getting. Actually starts and idles smooth as glass. if i had to describe exact symptoms id say...its like the feul lines are all fulled up and as i apply throttle, i consume the fuel and have to wait for the pump to "catch up"..but all fuel tests are cool. I would agree with massive unmeasured air causing lean...but can pcm really correct that much? and ...in order to compensate shouldnt i see poor economy...HA thats funny using the word economy in a post about a 454...anyway if all i wanted was economy id buy a toyota. just really frustrated not like the good ol days of carbs
