yes very…1200cc injectors+dual walbro’s+e98+Evans rich tuned+my lead foot=6mpg’s is my thought…point is im not driving it to the track unless a track pops up in Butler anytime soon. Im wrong by the way…I got 86 miles from a full tank of gas, so say it was a true full tank and i ran it completely empty thats 86miles/13.2gallon=6.51mpgs???
