i've been doing some AFR data logging and am up to 15mpg on the freeway and 10-11 mpg around town and i've noticed that the hood scoop is not conducive to good mpg numbers so mine is completely blocked off, it seems there is a vacuuming effect at freeway speeds 60-75mph that causes the AFR's to go way rich, food for thought?….roush 427R motor single plane intake, pro-system custom built carb flows 996cfm, tko600rr trans, stock rear end gears...
