I put a lot of highway miles on my car and I got roughly 340-350 on a tank before installing my AEM V2, now I am getting around 350-360. My fill ups at the pump are between 9 and 10gallons. Its also worth noting that while on the highway I never drive under 80mph unless stick in traffic. I know if I slowed her down to 70mph I would probably get even better numbers

 

whi is my mileage sooo bad compared to all of you with modded motors? even if i drive well mannered, i only get a fraction of what you get. i have changed fuel filter. new spark plugs, change oil with full synthetic, used seafoam amoung other additives at one point. cleaned air filter...mileage is only 146kilometers so like 90k miles or less, so what is going on. if i drive nuts i notice little change to when i shift at 3 grand, no sudden pumps of gas... what do i need to do???????????

 

my hatch gets about 350-370 all city and 400-420 highway its almost stock just exhaust now my fit gets just 230-270 city and 300- 310 highway[:@]
