Thread: gas mileage

    gas mileage

    I know in a perfect world everyone would be so rich that gas mileage wouldn’t be a concern but we live in this world. So what kind of gas mileage are you guys getting with full bolt-ons and a tune? I know after I put the HD2 in my 60e i picked up 1.5/2 mpg

    i get 16 - 17 maybe better on the highway at 65mph. I get up 75-80 and it drops to about 14 mpg. Around town it does pretty good prolly 15-16, but if im in the throttle it sucks like goosing it around town and messing with peeps i prolly get 8-9 mpg oh and when im the 200 tune it really blows
