i think im not getting enough miles per gallon.. i have a SSAC header without oxigen sensors . maybe thats it right ? that i dont have any oxigen sensor ?
EDIT- my motor is a VE, i got 180-230 miles per tank, without passing of 4000rpms. i know this is a all motor thread but is the only one i have seen regarding gas millage .
nd my motor has high compression so i dont know if this affects .
